Abstract
The grid-convergence behaviors and accuracy of the cut-cell method in viscous flows are investigated n a study. To mitigate the complexity of grid-generation methods, a simplified cut-cell method for high-Reynolds-number flow simulation is proposed for Cartesian grids. The small or split cells that often appear in the cut-cell method are eliminated by a simple projection strategy that conserves the original Cartesian grid’s data structure. To validate the accuracy of the solutions obtained by the new method, the simplified cut-cell method and IBM are compared directly on the same computational fluid dynamics (CFD) solver. Compressible laminar and turbulent flows are solved. In particular, a wall function is combined with the two methods to reduce the computational costs in turbulence calculations.
