Analys av turbulensmodeller för CFD

This thesis has been a part of Forsmarks Kraftgrupp AB's evaluation of a turbulencemodel used in simulation of turbulent flow called PRNS (Partially Resolved NumericalSimulation). This model has promising properties and may be of use in savingcomputational resources. The purpose of this thesis was to analyze this model andcompare it with industrially applied models such as k-omega SST and LES (Large EddySimulations).PRNS works as a hybrid of the k-omega SST and DNS (Direct Numerical Simulation)where a constant, RCP (Resolution Control Parameter) with a value between 0 and 1are selected. This constant is then used in the calculations and determines thebehavior of the simulation. When RCP is set to zero the equation are the same as fora DNS simulation and when RCP is set to one the equations for k-omega SST issolved.

Bostaden – sedd ur kvinnligt perspektiv

Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

Djurhållning och hälsoproblem i svenska mjölkgetbesättningar : sett ur djurägarperspektiv

Very little is known about the health situation amongs Swedish dairy goats. The population of Swedish dairy goats can only be estimated, and that number is somewhere .

Hydraulisk och termisk grundvattenmodellering av ett geoenergilager i Stockholmsåsen

Geothermal energy can be extracted from an aquifer, where the groundwater is used as heatexchange medium while heat and cold are stored in the surrounding material in the aquiferand to some extent in the groundwater. Application of aquifer storage for the use ofgeothermal energy is mainly used in large scale facilities and is limited to sites with suitableaquifers in the form of ridges, sandstone and limestone aquifers.Löwenströmska hospital in the municipality of Upplands Väsby, north of Stockholm, islocated nearby the northern part of the Stockholm esker. This means that it can be profitableand environmentally beneficial for the hospital to examine the possibilities of aquifer storagein the esker material next to its property.The purpose of this master thesis has been to investigate if geothermal energy storage with aseasonal storage of heat and cold can be applied within Löwenströmska hospital?s propertyarea using groundwater modeling. A hydraulic groundwater model was constructed inMODFLOW based on a simplified conceptual model of the groundwater system.

Affärsmodeller inom IP-telefoni

When communications traffic increasingly turned into data, IP telephony became a disruptive technology for the telecommunication business. IP telephony was a hot topic when voice over IP services started to become available to consumers in the 1990s. The new technology changed the rules of the game and many new actors entered the market.The purpose of this study is to describe, study, and analyze how the business models of the Swedish telecom sector developed in the middle of the 2000s. The study is delimited to the Swedish consumer market for telephony.The study is built mainly upon deep interviews with 24 prominent persons in the telecom sector in 2006. To aid understanding, two telecom companies that have been chosen to represent different kinds of actors are described and analyzed more closely.

Från konsument till medproducent : förekomsten och utvecklingen av Community Supported Agriculture i Sverige

Community Supported Agriculture (CSA) is an unconventional model of agriculture expected to contribute to a more sustainable food supply and a sustainable landscape; the development of rural areas; a stronger relationship between producer and consumer and a healthier diet. This study, with a focus on food production and the link between the producer and consumer, describes the origin and current development of CSA in Sweden, including the prerequisites for CSA in a Swedish context. Organizations and entrepreneurs working with CSA and related projects are identified and interviewed. The notion of CSA in Sweden is still in its infancy, but a rapidly growing interest currently can be detected. The fact that the identified CSAs are found in different Swedish regions with variations in degree of urbanization and intensity of agriculture indicates that the prerequisites are there for the concept to grow, both in rural as well as urban areas.

När barn behöver stöd i skolan : Direkta och indirekta målformuleringar

The aim of this thesis was to investigate the relation between different kinds ofremedial teaching models, not specifically addressed to pupils with physicaldisabilities, in the Swedish school context, and to describe and analyze theobjectives related to each model. Research focus was held on professionaldescriptions of school related problems and arguments for different kind of models,but also on objectives formulated in Swedish school policy. As theoretical toolswere used discourse analysis and interpretive policy analysis. The concept ofalienation as it appears throughout Foucault?s work was also used to understand howdifferent knowledge fields as education, special education, psychology and medicinedivide themselves from each other.

Anpassat växtmaterial för skärgårdsmiljö - Tjörn

In 2007 Swedish Meats, the dominant Swedish meat-producers cooperative sold its slaughtering and processing industry. The goal of a producer cooperative structure is to create value for members through vertical integration, and to strengthen members? market position. When Swedish Meats sold the slaughtering and processing components, it ceased in some respects to serve the function of a cooperative. This is a lost opportunity for both members and non-members, because Swedish Meats as a functioning cooperative could have exploited its dominant market position to positively effect producer?s prices.

?TRO OCH TVIVEL? En studie om kristen tro i ett en g?ng sekul?rt men numera postsekul?rt Sverige

This thesis explores how participants and leaders in ?Alpha?, an introductory course to the Christian faith, relate to and practice faith in Sweden. Sweden has often been viewed as a secular country where religion has been seen as irrational, outdated, and as something that belongs to the other but not to the self. Through the eyes of Swedish Christian practitioners, this study explores what kind of relationship my informants have to Christian faith and God while also exploring how living in a secular or post-secular context affects their way of believing and interpreting God and the stories written in the Bible. Furthermore, understanding of the Bible is viewed in the light of the concepts ?mythos? and ?logos? which highlights where Western explanatory models fail to explain and understand mythological stories.

Läsinlärning för elever som har svenska som andraspråk : Olika metoder

In school there are many pupils with Swedish as their second language and these pupils often have less basic condition compared with pupils with Swedish as their mother tongue and the most common root cause is lack of language knowledge, also the time spent in Sweden matters.I have trough questionnaires and literature studies investigated if there, for pupils with Swedish as their second language, is an easier way to figure out how to read and write in Swedish using fiction literature as learning material compared with ordinary ways.In the questionnaires that I performed participated a number of teachers that teach Swedish as a second language. These teachers all work in schools with a big share of pupils with Swedish as a second language.I also tried to evaluate if there was a difference between teachers with a graduation in Swedish as second language compared with these who don?t have a graduate but still work with these pupils.The result shows that I discovered that only the graduated teachers have used fiction literature as a learning material in the daily work and have experienced good results from the pupils, they also knew why they used fiction literarture for reading and writing training.As a teacher it is very important to have the knowledge regarding children that have Swedish as a second language, to be able to support them in a correct way.Despite the pupil can?t speak or read the new language, it has feelings and knowledge about the circumstances that they can?t express.The teachers mission is to knew and have understanding for these circumstances.Keywords: Pupils with Swedish as second language, learning to read and write, fiction literarture, school..

Demokratisk rådgivning : En studie av inflytande hos pensionärsrådet och ungdomsfullmäktige i Karlstads kommun

The purpose of this study is to determine if and how municipal consultative entities through influence may affect the legitimacy of the Swedish democratic model. The study aims to do this through analysing the opportunities for influence present with the Youth Council and the Council of the Retired in Karlstads municipality, to determine how the councils may affect political participation and the role of elected representatives. To do so, the study asks the following primary research question:"What requisites for influence are present for participants of municipal consultative entities, as found for the representatives of the youth and the retired within the framework of their participation in the Youth Council and the Council of the Retired in Karlstads municipality?"The study answers this research question by dividing it into one question of policy and one question of democratic perspective, and investigating these matters through nine snowballing interviews with the decision makers, organisational actors and participants of the councils. The information from the interviews is then analysed per council through a framework of democracy theory, policy process theory and organisation theory.

Framgångsrik Implementation av Lean : Förbättrade möjligheter med implementationsmodell

Lean production is the name given to Toyota?s Production System (TPS) by the west. The continuous improvements of their operations through Lean has made Toyota into the largest car manufacturer in the world. This, in turn, has led to several studies regarding both Toyota and their system as to find ways to apply Lean in other organizations. Even so, over 90 percent of all companies fail to implement Lean.

Samlande vs. tillgängliggörande : En jämförelse mellan två förvärvsmodeller på akademiska bibliotek

The aim of this Master's thesis is to examine what effect two different models of acquisition have on user satisfaction with information resources at academic libraries. The two models examined are the traditional model where a subject specialist librarian makes the selection, and the user-governed model where the larger part of the selection is based on user requests. The scope is the libraries of Roskilde University, which employs the traditional acquisition model and Malmö University, which employs the user-governed. Both libraries have a user-oriented approach to acquisition. The study encompasses a close examination of the acquisition policy through document analysis and interviews with the librarians in charge of acquisitions at each university, as well as a user-satisfaction survey among the professors and senior teachers on two faculties at each university respectively.

Skapande av organisationskunskap i små, unga forskningsintensiva företag : En studie av tre företag i Uppsala

Because of among other things the globalization and a focus on core competencies knowledge has become very important for the companies of today, especially for research-intensive companies. The problem is that the companies become more sensitive to how knowledge is created and spread, that is, how organizational knowledge is created. Especially sensitive are companies who are small, young and research-intensive. The purpose with this thesis is to explore how organizational knowledge is created in small, young and research intensive companies.The theory is based on a five-phase model of organizational knowledge creation and four modes of knowledge conversion described by Nonaka and Takeuchi (1995). These concepts constitute the foundation of the analytical model used in the thesis.The study is carried out by qualitative, highly structured interviews with low standardization.

"Hur skall detta ske? Jag har ju aldrig haft någon man." : Hur feministiskt exegetisk litteratur bidragit till förståelsen av Luk 1:26-38 åren 1977-2012

This paper aims to explore the possibility of reading the Temple cleansing stories of John and Mark through Bruce J Malina?s honor/shame model, as E. Randolph Richards do. The analysis searches in John?s and Mark?s Temple cleansings for the presence of the notions of honor and shame, as Malina uses those concepts in his model.
