摘要
Abstract
This paper,by adopting CFD software and combining experimental studies,investigates the flow and heat transfer properties of rhombic pin-ribbed PCHE at different heat flow densities and Reynolds numbers.The results show that both h and Nu of the PCHE channel increase with the increase of heat flow density and Reynolds number,yet the growth rate becomes smaller and smaller.ΔP and f of the PCHE channel increase with the increase of Reynolds number,while ΔP and f decrease with the increase of heat flow density.To compare the results of experimental measurements and simulation calculations,it is found that the experimental values have the same trend with the simulation values with slightly higher experimental measurements,which verifies the accuracy of the simulation model.关键词
