摘要

Three-dimensional numerical analysis of the flow around rectangular cylinders with various side ratios, D/H, from 0.2 to 2.0, was carried out for Reynolds number of 1000 by using a multi directional finite difference method on a regular-arranged multi grid. The predicted results are in good agreement with the experimental data. It is found that fluid dynamic characteristics of rectangular cylinders alternate between the high-pressure mode and the low- pressure mode of the base pressure for D/H=02-0.6. We show that this phenomenon is induced by the change of the flow pattern around rectangular cylinders.
