| Abstract: | In order to verify the correctness of the model,a 3D and a 2D numerical models of a parallel flow evaporator were established.According to the correct models,this paper analyzed the effect of face air velocity on the air-side parallel-flow type evaporator by fluent software and 3D coupled heat transfer model.Air-side main configuration parameters(fin pitch,fin thickness,blind pitch and blind angle) with different face air velocity played different roles in the heat exchange as well as pressure drop. |
