Optimization Study on Phase-change Heat Transfer of Plate Heat Exchanger with Fusiform Dimples
摘要
Abstract
ANSYS Workbench is widely used for multiobjective optimization,by which we made an optimization study on phase-change heat transfer of the plate heat exchanger with the fusiform dimples.And the influence of R,L,D on the thermal-hydraulic performance was explored with Nu,f and PEC serving as the objective function.The results showed that the volume fraction of water vapor around the fusiform dimples was significantly higher than the smooth plate which was far away from fusiform dimples.It proved that the plate with the fusiform dimples has a very good strengthening effect on phase-change heat transfer.And that with the corresponding parameter setting the thermal-hydraulic performance of the fusiform dimples was higher than the circular dimples.Within the scope of the study,the optimal structure parameters was R =3 mm、L =5 mm、P =24 mm,and the objective function was PEC =2.16,Nu =137.15,f=0.187 4.关键词
