The convection heat transfer of forced air flow across a triangle staggered tube bank embedded in porous metal foam was investigated experimentally.The results show that the resistance of fluid flow increases obviously because of the porous metal foam

but the increase rate decreases with the increase of Reynolds number.Porous metal foam greatly enhances the convection heat transfer.The enhancement effect decreases with the increase of Reynolds number.In the experimental range

the flow resistance increases 10.109—12.727 times that of plain tube bank

while the enhancement of convection heat transfer is 2.08—2.78 times.The correlations for non-dimensional resistance coefficient and the Nusselt number are obtained in the experimental range.It is concluded that the porous metal foam is more suitable for the low velocity of fluid from aspects of heat transfer enhancement and flow resistance.
