The Analysis of Square Enclosure Air Layer's Heat Transfer in Building Materials

Abstract:

This paper using Fluent Software to numerical simulate the heat transfer in square enclosure cavity air layer in different thickness and heights.By analysed the simulation results, we found that the best thickness in it is 20mm .Then we respectively used empirical formula as well as simulation results to calculated the heat transfer coefficient in air layer. The results showed that both numerical were very close, the calculation of heat transfer coefficient was consistent with the simulation results obtained by the rules.
