| 内容記述 | A method to generate a grid for an enclosed or internal flow region with guaranteeing grid orthogonality at the wall boundary region as well as smooth grid-line connections is presented in this paper. The computational region is divided into three types of zones to which the hyperbolic, elliptic, or hyperbolic-elliptic blended methods of grid generation are applied. The hyperbolic grid method is applied to a zone next to wall boundary in order to get the excellent grid orthogonality. While the elliptic grid method is applied to an inner zone where the grid smoothness is important. These zones are connected through a transitional zone whose grid is generated by the hyperbolic-elliptic blended in order to avoid sudden change of grid property. In order to obtain superior grid orthogonality at the hyperbolic grid as well as superior robustness at the elliptic grid, an upwind-biased finite-difference formulation is introduced. A new pseudo-time iteration method using the stable rational Runge-Kutta scheme is introduced to solve resultant discretized equations for further robustness. The generated grids for complex geometries demonstrate the performance of the method. | |||||||||
