Computations of Jet Impingement on a Flat Surface,

Abstract

An incompressible, inviscid rotational flow model is used to represent the normal impingement of axisymmetric jets and the oblique impingement of two-dimensional jets upon a flat surface. The Poisson-type equation that results from this formulation is cast into suitable finite difference form and solved by relaxation techniques. Results, in terms of the ground plane pressure distribution, centerline velocity decay, and oblique impingement flow field structure, compare well with observations. (Author)
