摘要
对特征无反射边界条件中角点耦合处理方法进行了分析,提出了新的角点耦合处理数学方法.对空间发展的可压缩圆孔射流进行数值模拟,并将模拟结果与试验值进行了对比.结果表明:新的角点耦合处理数学方法在处理声波反射方面是有效的,数值模拟结果与试验值吻合较好.
Based on analysis of the coupling treatment method for corners in characteristic non-reflecting boundary conditions, a new mathematical method for corner coupling treatment is put forward. Numerical simulation has been conducted on a spatially evolving compressible round jet and the simulation results are compared with experimental data. Results show that the new mathematical method for corner coupling treatment is effective in the aspect of acoustic reflection treatment and the simulation results properly fit the experimental data.
