dc.description.abstract Abstract The flow between cooling fins of the ABB HXR 400L electric motor was simulated numerically by calculating one fin space and its surroundings. FINFLO flow solver, developed at Helsinki University of Technology, was used in the simulations. For the turbulence modelling Chien's low-Reynolds number k-ε models were utilized, since in this case k-ω model did not seem to work properly. Main result A suitable grid with 750 000 cells was introduced. Different variations of a computational domain and boundary conditions were tested and they affected significantly to the computational results. The results were compared to measurements made by 'cold' motor, i.e. only the fan was rotated. The calculated velocity was quite near the measured values at the first half of the fin, but differed significantly towards the end of the fin. Also the simulated flow seems to stay between the fins too well. en
