【摘要】：利用流體力學(xué)方程的積分形式給出非結(jié)構(gòu)移動網(wǎng)格上離散格式,利用自適應(yīng)移動網(wǎng)格方法移動網(wǎng)格,進(jìn)而得到網(wǎng)格速度.對振動Naca0012翼型問題,分三種類型確定網(wǎng)格速度,再結(jié)合Riemann問題的解法器構(gòu)造數(shù)值通量,得到移動網(wǎng)格單元上新的物理量.數(shù)值實驗表明這種格式同時具有高效、高分辨率的特點.
[Abstract]:By using the integral form of fluid mechanics equation, the discrete scheme on unstructured moving grid is given, and the adaptive moving grid method is used to move the grid, and then the grid velocity is obtained. For the vibrating Naca0012 airfoil problem, the grid velocity is determined in three types, and then the numerical flux is constructed with the solver of the Riemann problem, and a new physical quantity on the moving grid element is obtained. Numerical experiments show that the scheme has the characteristics of high efficiency and high resolution at the same time.
