The proposed flow in a 3-D cubic cavity is driven by its top and bottom walls moving in perpendicular directions. This flow is a representative of genuinely three-dimensional highly separated vortical flows with elevated helicity yet having simple single-block cubical geometry of computational domain. The elevated level of helicity in the proposed flowfield is caused by motion of a wall in the direction of axis of primary vortex created by a parallel wall. The flowfield is obtained numerically…
