Prediction of effective heat transfer performance of metal foam heat exchangers

摘要

A numerical investigation of heat transfer performance of metal foams is conducted to predict the local temperature distribution of the flow and metal foam ligaments . Th is examination will serve as a stepping stone to better optimize metal foam heat exchanger designs. An i dealized Weaire - Phelan metal foam model is used in this investigation. The magnitudes of local temperature hotspots differ due to the foam’s geometric profile, namely the foam fibre thickness. The heat transfer characteristics of the fouling zone is predicted based on the foam wall’s temperature distribution hot spots.
