    View Abstract

    Three dimensional separation is a completely different phenomenon from the familiar two dimensional separation. In three dimensional flows, there is a spanwise flow that develops in addition to the two dimensional separation due to the interaction of the lateral wall. This spanwise flow causes the creation of spanwise vortices that have a different shape if they are viewed in a two dimensional projection. Results are shown for the flow over a three dimensional backward step and around a surface mounted cube that verify these phenomena. The numerical experiments have been performed by directly solving the Navier Stokes equation with Galerkin finite elements in computational domains that have been designed as idealized wind tunnels with appropriate boundary conditions.
