Vorticity Waves in Shear Flows
Journal Title: INCAS BULLETIN - Year 2015, Vol 7, Issue 1
Abstract
The main purpose of this paper is to bring about the vorticity-creation process at the boundary surfaces on one hand and to understand the interaction of concentrated vorticity structures on the shear flow on the other hand. The paper address the simulation of flow visualization of the vortical structures accounting for both the circulation and the degree of concentration of vorticity via the exact nonlinear solution of Stuart for an inviscid unsteady mixing layer. At a fixed volume of circulation an increased concentration of vorticity is provoked by decreasing the area containing most of the vorticity, and then it spreads over an increased area of the flow. A concentration parameter characterizing vorticity is defined and flow patterns, representing waves travelling in the flow direction are found for different combinations of vorticity concentration and circulation.
