【摘要】：利用流体力学方程的积分形式给出非结构移动网格上离散格式,利用自适应移动网格方法移动网格,进而得到网格速度.对振动Naca0012翼型问题,分三种类型确定网格速度,再结合Riemann问题的解法器构造数值通量,得到移动网格单元上新的物理量.数值实验表明这种格式同时具有高效、高分辨率的特点.
[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.
