摘要
为提高流体机械在应用中相对总压的效率,基于CFD法设计流体机械。通过输入流体机械几何边界条件,并施加壁面函数,生成流体机械空间离散格式网格。在此基础上,利用CFD法差分计算流体机械离散控制方程,输出流体机械收敛准则,基于Interface流场分析流体机械三维模型,并模拟运行,达到标准后完成基于CFD法的流体机械设计。结果表明,设计的流体机械相对总压效率明显高于对照组。
In order to improve the efficiency of fluid machinery relative to total pressure in application,the fluid machinery is designed based on CFD method.By inputting geometric boundary conditions of fluid machinery and applying wall function,the spatial discrete grid of fluid machinery is generated.On this basis,CFD method is used to calculate the discrete control equation of fluid machinery,and the convergence criterion of fluid machinery is output.The three-dimensional model of fluid machinery is analyzed based on Interface flow field,and the operation is simulated.After reaching the standard,the fluid machinery design based on CFD method is completed.The analysis of design and application examples shows the relative total pressure efficiency of the designed fluid machinery is obviously higher than that of the control group,which provides a certain reference for the application of fluid machinery.
