The proposed Project will make significant contribution towards the both fundamental understanding of heat transfer enhancement using dimpled surfaces and the design of heat exchangers and, in particular to the application of dimpled surfaces in air conditioning and refrigeration industries. Unlike the previous CFD studies which have been made on the assumptions that the flow is steady and decoupled from the heat transfer calculations in this Project the fully coupled problem will be solved, in which unsteady flows are allowed to occur over a dimpled surfaces. As a result we will be able to more accurately determine the resultant effects on the pressure drop and heat transfer.

该项目将对利用凹坑表面强化传热的基本理解和热交换器的设计做出重大贡献，特别是对凹坑表面在空调和制冷行业中的应用。 与之前的CFD研究不同，在本项目中，CFD研究是在假设流动稳定且与传热计算分离的基础上进行的，完全耦合的问题将得到解决，其中允许在凹坑表面上发生非稳定流动。 因此，我们将能够更准确地确定对压降和传热的综合影响。
