✦ Synopsis

Design optimization of ¯uid-thermal systems has been an area of signi®cant research interest for the aerospace and automotive industry. The subject studies the modi®cation of internal and external ¯ow passages under certain speci®ed objective constraints while satisfying the governing ¯ow equations. Amongst various available optimization procedures the analytical sensitivity analyses-based optimization is arguably the most ecient design tool for complex multi-dimensional practical problems. In this paper, we augmented the analysis capabilities of the computational ¯uid dynamics (CFD) code with design sensitivity analysis (DSA). The design sensitivities are computed eciently via analytical dierentiation methods. The CFD±DSA codes are then combined with numerical optimization schemes. Finally, CFD±DSA design optimization algorithm is applied to the optimization of heat exchanger ®n and HVAC duct systems.
