Abstract

The coherent wake structures behind a rectangular prism at different incidence angles are numerically studied at \(Re=250\). The results indicated that changing the incidence angle altered the critical Reynolds number at which the wake transitions to unsteady flow. The variation in wake dynamics and evolution of vortex structures are evaluated and characterized at high incidence angles. The change in the wake size and surface pressure distribution due to variations in the incidence angle are also related to the change in wake topology.
