Abstract
A new finite-difference technique, designated EMIT, is presented for calculating flows that are parabolic (that is, boundary-layer type) in some regions and elliptic in others without recirculation. The technique uses velocities and pressure as the dependent variables, and employs a marching procedure in all regions of the flow, wherein calculations are made along only one plane of the flow domain at a time, and the entire planes are visited in an ordered sequence. An application of the method is made to the plume in calm, stably-stratified surroundings. For this test case, a comparison is made between the EMIT and the SIMPLE procedure of Patankar and Spalding, and the EMIT algorithm appears to be more efficient than SIMPLE.Keywords
