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.

Brand equity and corporate responsibility : a review of brand valuation methods

During the last decades, brand equity has been a priority topic for both practitioners and academics. In accordance with the structural changes in the economic settings caused by the so-called "new economy", corporations being confronted with a shift on perceived business value structure from tangible assets to intangibles. On the other hand firms increasingly are adopting more responsible behaviour towards their societies. In this context, one critical question is to understand how corporate conduct may affect brand equity. The purpose of this study was to find how brand equity (BE) measurement methods embrace corporate responsibility (CR), based on a literature review.

This master thesis was done for a company called BRUKS which is active in woodprocessing,bio-energy and bulk material handling industry. The idea for the master thesis wasto develop a new reclaiming method for silos where wood chips are being stored. A mediumsegment of between 1000 ? 5000 m3was defined as the segment with the most sales potential.Two different concepts were produced, one for new constructions and one for rebuildingalready existing silos.In the beginning of the master thesis a lot of time was spent on visiting different BRUKSoffices and customers to get an overview of the industry and the product. This informationwas the basis when the idea generating phase began.

När visionen mötte verkligheten : en undersökning om hur arkitektur kan styra människors rörelser på studentbostadsområdet Vildanden

The essay treats how an architect can direct motions of humans with architecture. This is made through an investigation of how the architect Bengt Edman has treated accessibility and motions when creating the student housing complex Vildanden and how it has affected the motions of humans within the area. To visualize how Vildanden relates to the rest of Lund I have made a comparative study with the city planning ideals that prevailed in the period when the area was built.The essay is based on the author's own observations through a phenomenological perspective and a field study including observations and a literature study..

Starka kvinnor och männen i deras skugga : En maskulinitetsstudie i Cirkeln

This paper investigates the relationship between the two modernist writers Katherine Mansfield and Virginia Woolf. The two authors had a frail and complicated friendship that influenced their fiction and fictional characters more than the general public knows. My paper investigates how Woolf can have found her fictional story ideas direct from their friendship. With a comparative theory I?m finding and giving examples of how their friendship is reflected in their fictional stories, and I?m backing up my examples with citations from their own diaries, letters and notebooks.

Slusseneländet

Stockholm is constantly growing and changing. Despite this, for various reasons, it is difficult to execute large building projects. With starting-point in decision making theories we have tried to investigate these difficulties. More specifically we have chosen to study why it has not been possible to rebuilt Slussen in Stockholm. To help us structure our study we have based our research on another large comparable building project, the Globen City project.

Förbättrad vakuumtätning mot kabeln under plastextruderingsprocessen

This thesis is about developing a design that provides improved vacuum seal between a lead coating and a plastic coating during plastic extrusion processes of cables. This report is a part of the course MSGC 17 for Bachelor Engineers in mechanical engineering.The work is performed at Nexans Norway AS in Halden where they have a production of high voltage cables for sea-, and offshore industry. A problem they face is that they do not get enough good seal at the attachment to the plastic extrusion machine. They want to achieve a vacuum between a lead coating on the cable and a plastic coating of the cable for plastic extrusion, which is something they do not achieve today. The thesis is thus to come up with a design that provides better sealing against the cable.The work involves a construction part with the phases of product development processes.
