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