摘要 采用基于Menter SST两方程湍流模型的DES方法,数值模拟开式凹腔在跨声速条件下的非定常流动特性.计算凹腔底部和后壁面上的点的声压级频谱以及总声压级,证明在第二噪声模态上的声压级最大. Menter SST based detached eddy simulations (DES) is performed for transonic flow over an open cavity to study unsteady flow and acoustic fields.Sound pressure level (SPL) spectra and overall sound pressure level(OASPL) on surface of the cavity floor and the cavity back wall are computed.It shows that the second mode is dominant with the largest magnitude in SPL.
