Abstract
Computational Fluid Dynamics (CFD) has been increasingly relied on as an important tool for the aerodynamic design. However, mesh generation for 3D complex geometries is still the most time-consuming task in CFD. Recently, Cartesian grid methods have become popular because of their advantages of fast, robust, and automatic grid generation. Authors proposed a new approach based on a block-structured Cartesian grid approach, named Building-Cube Method (BCM, [5]). This method is aimed for large-scale, high-resolution computations of flows. In the original BCM, however, the wall boundary is defined by a staircase representation to keep the simplicity of the algorithm. Therefore, to resolve boundary layers, vast amounts of grid points are required especially for high-Reynolds number flows of practial applications. In this paper, a new embedded boundary treatment suitable for high-Reynolds viscous flows on BCM is proposed. The scalability performance on cluster comput ers is also investigated with this method.
