摘要:
针对梭型凹坑凸胞板式换热器的凹坑流道,采用ANSYS Workbench进行了相变换热优化研究.以综合传热性能因子PEC、Nu、f为共同的目标函数,研究了梭型凹坑半径R、梭型凹坑长度L、凹坑分布间距P等结构参数对梭型凹坑凸胞板式换热器相变换热的性能影响.研究结果表明:梭型凹坑处水蒸气的体积分数明显高于平板处的水蒸气体积分数,说明梭型凹坑凸胞板对相变换热有着很好的强化作用,并且梭型凹坑流道的换热性能优于相应参数下圆形凹坑的换热性能.本研究中得到的最优结构R=3mm、L=5 mm、P=24 mm,此时对应的PEC=2.16、Nu=137.15、f=0.1874.
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.
