摘要: 详细分析特征无反射边界条件(Characteristic Non-reflecting Boundary Conditions)中边耦合处理方法,提出耦合处理的数学方法,数值模拟表明,该方法处理声波扰动时有明显的优势.对可压缩圆孔射流进行直接数值模拟,结果与试验吻合较好,表明提出的耦合边处理的特征边界数学分析方法是可行的.

Abstract: A mathematical treatment of edge in characteristic non-reflecting boundary conditions is developed.Several numerical simulations show that this method is benefit for treating of waves.A spatially evolving compressible round jet is simulated with direct numerical simulation method.Simulation results are compared with experiments.It suggests that the method on edge boundary conditions is convincible.

Key words: characteristic non-reflecting boundary conditions, direct numerical simulation, round jet, edge boundary conditions Received date
