【 摘 要 】

This article presents the numerical studies on separate flow across elliptical cylinders of various axis ratios (AR) in the laminar region. The simulations calculated the laminar separation Reynolds number that marks separation of flow from surface and the critical Reynolds number that represents transition from steady to unsteady flow. The separate angles are expressed as the function of the axis ratio and Re in laminar region. The results are in good agreement with existing data.
