Study on Heat Transfer Correlation of the Air-conditioned Bus Exterior Surfaces

摘要：

This study analyzes and compares the limitation about the heat transfer coefficient of airconditioned buses exterior surfaces in some literatures, and attempts to educe new integrated correlations.In this paper,numerically calculating the nature and forced convection on the air conditioned bus exterior surfaces, the author thinks that there are different heat transfer laws over different surfaces.As a result,the new integrated correlations of the average heat transfer coefficient on the exterior surfaces are obtained,which related with the convection style and the surfaces relative place. Comparing with the literatures formulas calculation, the new correlations result is in the middle and changes bigger than the literatures with the bus moving velocity.
