在本文中，我们报告了一个新的并行求解器的发展，通过重建（CPR）的粘性流动的移动和变形网格的校正程序。通过对全四边形网格的运动和变形非结构网格的通量导数的精确处理，发现在运动和变形网格上不需要几何守恒定律，自由流守恒是自动满足的，并用一个基准算例对CPR程序进行了验证。得到了精度的最优阶数。随后，它被用来研究运动和变形网格上的粘性流动。CPR方法比SD方法更快，并且几乎与SD方法一样精确地求解具有移动边界的粘性流动问题。
In this paper, we report the development of a new parallel solver using the Correction Procedure via Reconstruction (CPR) for viscous flows on moving and deforming grids. By employing an accurate treatment of flux derivatives for moving and deforming unstructured grids consisting of all quadrilateral cells, it is found that the Geometric Conservation Law is not explicitly required, the free-stream preservation is automatically satisfied.The CPR code is verified using a benchmark case for a moving inviscid vortex on moving and deforming grids. The optimal orders of accuracy are obtained. It is subsequently employed to studyviscous flowson moving and deforming grids. The CPR method is faster than and nearly as accurate as the SD method for solving viscous flow problems with moving boundaries.
