This paper present an analytical and experimental investigation of the performance of metal foams in an impinging flow application. Microstructures of the foam as well as the foam-to-solid braze interface are presented. Aditionally, the effects of brazing procedure on the performance of the heat exchanger are investigated and the results are compared to CFD analysis assuming perfect braze joints. Finally, the results are compared to commercially available micro-channel heat exchangers.
