湍流模型对过冷沸腾计算影响分析
Effect of Turbulence Model on Prediction of Subcooled Boiling
摘要
Abstract
The ANSYS FLUENT14.5 was employed to simulate the two‐phase forced convection subcooled boiling in a vertical heated pipe .Different turbulence models ,wall functions and two‐phase turbulence treatments were utilized to each of four sets of grids .Results were compared with experiment data to analyze the effects of grids , turbulence model ,wall functions and two‐phase turbulence treatments .The results of k‐εmodel show better agreement with experiment data than those of k‐ωmodel .Dis‐persed and Per Phase treatments for two‐phase turbulence parameters perform no better than Mixture treatment .The enhanced wall function can’t achieve satisfactory results for the grid with near wall function Y + ≈1 .关键词
