高压下打孔翅片通道内的流动换热性能

with the development of an internal compression process, study of fluid flow and heat transfer of perforated fin channels at high pressure is increasingly crucial. But most of researchs mainly focused on two aspects. On the one hand, studying that how to weak uniform flow distribution by using perforated plate fin heat exchanger, on the other hand, The airside thermal hydraulic performances of different finchannels are investigated numerically when fin thinkness is less than 0.3mm, the research of fluid flow and heat transfer of perforated fin channels is precious few for low temperature and high pressure. in order to design and optimize the plate-fin heat exchanger,The airside thermal hydraulic performances of different finchannels are investigated numerically.Firstly, the general behavior of flow and heat transfer in perforated finchannelsare analyzed.Secondly,Based on the analysis of a large amount of numerical data, general correlations of jand f factors are developed, and then comparing the value of j and f factors with experimental andnumerical simulation results, the results show that experimental and simulated values have good consistency. Finally, to evaluatethe performance of heat transfer enhancement for perforated fins.)
