… between fluid and structure is always presented. More precisely, the fluid flow affects the structure by applying force(s) on it and vice versa. As a result, the structure can move (vibrate) or deform. A good understanding of this problem can help to design the system in term of …
… analysis to create an understanding of the problem. This was followed by a flow analysis and a functional analysis to get a deeper understanding of the problem and structuring the machine's process flow and its features. The author then came to the conclusion that four stations …
… energy demands that are placed on the building. The unit chosen was a cross-flow heat exchanger, and this work is to compare it with two other heat exchangers to see if a more energy and cost efficient could have been chosen. The heat exchangers that was chosen for the …

… system analysis model for waste planing with tools for lifecycle and substance flow analyses. The model is used for calculating emissionsand energy consumption for a waste system. It is thought as a tool for simulating different treatment methods for liquid and solid waste in a …
… will affect the southeast region operations with regards to cost, routine, flow as well as the administration in general. In order to achieve this, two scenarios were simulated in Roadshow. In the first scenario, the fixed routes were kept but they were reorganized in order to …
This thesis describes a system for dealing with free surface fluid simulations, and the components needed in order to construct such a system. It builds upon recent research, but in a computer graphics context the amount of available literature is limited and difficult to …
en modellstudie vid dimensionerande flöde
… as a class 1B dam. This means that the dam must discharge a class 1-flow which has a return period of 10 000 years. The inflow into the dam has been calculated in an earlier report to 495 m3/s, with a waterline at an elevation of 126, 3 meters above sea level. The gravity dam …
… The model is for instance considering variations in temperature and height, flow resistance in lines and valves, component characteristics, fuel evaporation, leaks etc. Furthermore the pump current is treated by the diagnosis evaluation algorithm with purpose to judge whether …
Hur de termiska stigkrafterna påverkar ventilationseffektiviteten
… are being used in this model is the Navier-Stoke’s equation for Non-Isothermal flow, the relations for General Heat transfer and the relation for Convection and Diffusion. These relations exist as tools in COMSOL Multiphysics. It wasn’t possible to get the model to converge at …
… roundabout, Alt 2 is as good as Alt 3. With a desired increase of the traffic flow on Mästergatan, its intersection to the commercial area Myran may be crucial if it is not properly dimensioned. It is therefore important that the design of this intersection is thoroughly planned …
Evaluation of phosphorus leaching aftermanure application using lysimeter techniques
… of OVRP are typically recorded. This is generally explained by fast flows through macropores in the soil and through the drain tile systems. Solid manure was applied to the lysimeters equal to a normal agricultural load (30 tons per ha), and thereafter another three rainfall …
Syftet med arbetet var att undersöka möjligheten för optimering av produktflödet. Företagets produkter transporteras på ett transportband till en gemensam process. Det nuvarande flödet till processen är inte optimerat vilket resulterar i att processen körs ineffektivt …
Ett examensarbete om akustik- och brandkrav samt en jämförelse av energi- och fuktaspekter
… in Comsol. The results show that the concrete wall has a higher heat flow than the two wooden walls. VIP-Energy was used to calculate the energy consumption of a house with Kaufmanns construction and the concrete construction. Both of these construction systems fulfils BBRs …
… The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust …
