Abstract:	CFD optimizations are characterized by long and highly variable objective function evaluation times. The aim of this study is to improve the parallel performance using a new load balancing master-worker parallelization strategy. First the new method is introduced and compared with the standard parallelization strategy. Finally two illustrative examples are provided.
