| 摘 要： | 应用时空守恒元解元方法求解二维Navier-Stokes方程,将CE/SE方法应用于气动噪声的计算中,分别对低速流动的圆柱绕流及门式空腔的近场噪声问题进行了数值模拟。分析结果,流场解很好反应了流场的形态,得到的频率及声压级(SPL)分别与其它文献结果和实验结果吻合较好。结果表明了将CE/SE方法应用于声场模拟中的可行性。

| Abstract: | Based on the CE/SE method,the procedures were used for solving the 2-D Navier-Stokes equations.And The CE / SE method was applied to the calculation of aerodynamic noise.The near field noise of a cylinder and a door type cavity at low flow speed is numerically studied.The details of the flow were brought out very well.The computed frequencies and sound pressure levels(SPL) compared well with other literatures’ results and experimental results.The current method’s results prove that the CE / SE method applied to the simulation of aeroacoustics is feasible. |
