Résumé

This paper is a short review of recent studies on the optimization of conjugated heat transfer in fin arrays. First, some results are given on optimal geometries of single fins to get some general idea of how fin shape affects heat transfer. The main emphasis will be on fin arrays that can be solved with CFD. However, it requires extensive CPU time and is therefore often rejected in optimization in industrial applications. If the most time consuming phase of the solution, namely convective heat transfer, can be solved using analytical results, and if only conduction is solved numerically, we have a fast performing calculation model for design and optimization that helps to cut down CPU time by many orders of magnitude over conventional CFD solution. The accuracy of the model was evaluated by comparing its results to experimental, and in some simple cases, numerically calculated results. After being tested for accuracy, the model was used in multi-objective optimization of fin arrays cooled by natural and forced convection. The algorithm selected for optimization was the multi-objective version of the particle swarm optimization (PSO).
