“…For lumped method, a head losses model seems to be a natural choice given the fact the two methods have a global approach. For example, they are coupled in [5]. In our case, as we have several inlets and outlets as well as we do not know exactly the flow direction in certain zones of the machine, CFD is used.…”

“…This algorithm is used in a wide variety of fields (Poli [3]). In thermal engineering, Genetic Algorithm (GA) is the most used optimization tool (Gosselin et al [4]) but PSO, which has better performances than GA, is more and more used for heat transfer problems like in the study by Bornshlegell et al [5]. To be able to optimize the machine, the flow distribution inside has to be known for every geometrical configuration possible within the optimization space.…”

In this paper, the flow inside an electric machine called a starter-alternator is studied parametrically with CFD in order to be used by a thermal lumped model coupled to an optimization algorithm using Particle Swarm Optimization (PSO). In the first case, the geometrical parameters are symmetric allowing us to model only one side of the machine. The optimized thermal results are not conclusive. In the second case, all the parameters are independent. In this case, the flow is strongly influenced by the dissymmetry. Optimization results are this time a clear improvement compared to the original machine.
