Numerical simulation of a Viscous Axisymmetric Jet Impinging Normally on a Flat Wall

概要

An incompressible, viscous, steady flow model is used to simulate the normal impingement of an axisymmetric jet on a flat wall. The Navier-Stokes equations in stream function-vorticity form are solved numerically by means of a finite difference technique based on the fractional step method and on a combination of up-wind and central difference approximations. The velocity field and the pressure distribution in the impingement region are computed for a large range of Reynolds numbers : a transformation of the axial coordinate is used in the calculations for high Reynolds numbers. A comparison with experimental data for air jets shows a reasonable agreement.
