摘要：Metallic honeycomb material has one easy flow direction and superior surface area to volume ratio, so that it exhibits attractive heat capacity except for the high specific rigidity and specific strength. It is of great significance for multifunctional design to study its heat transfer efficiency subjected to forced convection. The heat transfer in the honeycomb material with a number of micro cells subjected to air convection is difficult to solve by using the method of computational fluid dynamics (CFD) directly, which is the obstacle to design optimization. Thus, it is very valuable in theory and application to develop a fast numerical algorithm. In this paper, the fast numerical algorithm for evaluating the thermal performance of metallic honeycomb materials was presented. It's an about 3-4 order of magnitudes improvement in computational velocity of this method compared with the finite volume method. The validity and applicability of the method were proved by two examples.
