… energy-efficiency measures. This work deals with the ability to control the flow through the heating system to achieve the desired comfort with as little energy as possibleA heating system contains of different parts, roughly speaking, you can divide it to three main components …
This paper describes the development of a simulation model for the ambulance flow in the Västra Götalands-region of Sweden, and an analysis tool for the output of the simulation model. The aim of the simulation model was to be able to evaluate the outcome from changes in the …

This paper describes the development of a simulation model for the ambulance flow in the Västra Götalands-region of Sweden, and an analysis tool for the output of the simulation model. The aim of the simulation model was to be able to evaluate the outcome from changes in the …
en simuleringsstudie med modellen SEWSYS
… with different rates of pollutant contribution. Then the stormwater flow and the contribution of pollutants was simulated with the model SEWSYS. The future aim is that the model will be able to simulate the contribution of pollutants for a variety of rains, for the whole …
… that a larger exhaust volume improve the turbine efficiency. Also an even flow of pulses to the turbine entry is positive for the efficiency. In engine test a single entry turbine has 4 % higher efficiency than a twin entry, this result correlate well to simulations. The smaller …
… engine has a tendency to knock. The simulations showed that the in-cylinder flow field creates a temperature distribution in the cylinder that is not uniform, possible increasing the knock risk close to the exhaust valves. Lastly, simulations of the combustion process were made …
… company, which is the basis for this thesis. Saab Dynamics wants to introduce simulation driven design. Since Saab Dynamics engineers have little experience of simulation, required a user methodology with clear guidelines. Due to lack of time, they chose to assign the task to …
… AB's evaluation of a turbulence model used in simulation of turbulent flow called PRNS (Partially Resolved Numerical Simulation). This model has promising properties and may be of use in saving computational resources. The purpose of this thesis was to analyze this model and …
… the river Byälven down to lake Vänern, are possible. One option is to reduce flow resistance along the river and thereby lower the maximum water level a given inflow would cause. Good knowledge of hydraulic and hydrological conditions is necessary in order to estimate the effect …
… for flooding have been developed. In the work, cross sections and the water flow have been measured. Moreover, an echo-sounding have been carried out in Funboån to map the bottom topography. From the bottom map and laser scanned data covering the study area, a terrain model was …
… the ventilation system is of the kind CAV (constant air volume) and the air flow is dimensioned for after recommendations from BBR and Arbetsmiljöverket in the office spaces. Consider that Embla 5 is an office building where the people only staying for 8-10 hours/day so was the …
Ett sammarbetesprojekt mellan fakulteten för teknik och naturvetenskap vid Uppsala Universitet och Fagrell produktutveckling AB
… Fagrell with verification and development of Fagrells prototype, Fundamental flow reactor, for flow chemistry. The uniqueness of Fagrells flow reactor is that it should be simple and affordable compared to competing flow reactors in the market. The verification was done by …
… The target has also been to evaluate if there is a possibility to improve the flow in the foundry and also the results. During the 20 weeks this work has been done at the foundry data has been collected and analyzed. It has been possible to confirm irregularities in the …
… The work has also included studying the possibilities to change the material flow in a positive way between the storage and the production when one is using existing buildings. During our work we have been used a simulation program called AutoMod, performing company visits …
… circuit with an active charcoal filter that adsorbs volatile anesthetics. The flow through the bypass circuit is generated by a pump and is controlled by a linear valve. The resulting performance of the patient simulator has fulfilled the requirements. A verification of the …
