A Study on the flow patterns around multiple cylinders on multiblock and unstructured grids

초록

The multi block and the unstructured grid generation method are applied to simulate the flow patterns and pressure distribution around multiple cylinders. Flwo patterns are simulated in a multi-block grid domain that is divided in several blocks and the meshes in each block are generated by algebraic and elliptic transformation methods. The constrained Delaunay triangulation method based on the Bowyer Watson algorithm is introduced to generate the unstructured grids. To verify the applicability of grids to flow computation, the flows around 2 cylinders are simulated and results are compared numerically and experimentally.
