… vessel. The results from the first, frictionless, model agree with similarsimulations and hand calculations for high pressures in the containment vessel. Thesimulations of the nuclear containment vessel show cracking in the concrete after10-11 bars of over pressurization. For …
… tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and soft ground. A comparison of theoretical data of different …
… in the bolted joint between the top part of the crane and the two leg parts. A simulation of the forces acting on the structure in heavy sea condition was conducted; these values were then used as input values in a Finite Element Method, FEM, analysis of the joint. Results show …
… ska tas. Optimeringen utförs med hjälp av en koppling mellan ett simulationsprogram och ett optimeringsprogram. Målet är att visa fördelarna med den undersökta metoden och vilka resultat som erhålls. Energieffektivisering av en byggnad kan vara en komplex uppgift med många …
… are studied.A model for energy savings have been developed, where a simulation program and energy calculation formulas have been used. The profitability of different energy efficiency measures are analyzed using the Life Cycle Cost, LCC method, using results obtained from the …
… will be used for distance learning in the future. StriSimPC can also be a simulation instrument for experiment and development activities based on resource efficient methods with low risk factors. In the future Simulators using serious gaming as StriSimPC may be used to create …

… possibleuse of different techniques to utilizethe phase change energy of water.Simulation shows that it’s possible toutilize the phase-change energy of afluid; however it’s not economicallyfeasible due to the thermodynamiceffects on the Carnot cycle. Further weconsider the …
Simulering och jämförelse av gamla och nya system
… demand increase or decrease depending on the changes chosen to be made, the simulation application IDA Indoor Climate and Energy was used. Simulations were made and compared for several cases, with two extreme cases as starting points. The cases were older and newer ventilation …
Metoder för att sänka återledningstemperaturen
… power plant, since drying the fuel causes an Increase of the heating value. Simulations has been made in Excel, and with use of linear regression, to find out if it is profitable. Data for this purpose has been supplied by the power company Skellefteåkraft and furthermore SMHI …
-Ur ett tekniskt och ekonomiskt perspektiv
… of debiting system that companies in Sweden have today. The model used in this simulation is self-made and enables variable energy consumption for the house as well as variable energy production for the wind turbine to give a truthful representation of the variations which occur …
… från Arboga reningsverk. Detta inkluderade både simuleringar i Benchmark Simulation Model no. 2 (BSM2) samt studier genom vattenprovtagning vid Arboga reningsverk. Vid simuleringarna genomförda i BSM2 påvisades en märkbart lägre halt totalkväve i utgående avloppsvatten efter …
… kan regleras så att syreöverskott undviks. Modellsimuleringar i Benchmark Simulation Model no. 1 (BSM1) användes för att jämföra snabb och långsam ammoniumåterkoppling samt olika typer av syrehaltsprofiler inför försök i full skala. Modellen byggdes om och kalibrerades för att …
