A numerical procedure for calculating partly elliptic flows
Abstract
A new finitedifference technique, designated EMIT, is presented for calculating flows that are parabolic (that is, boundarylayer 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, stablystratified surroundings. For this test case, a comparison is made between the EMIT and the SIMPLE procedure of Patankar and Spalding (1972), and the EMIT algorithm appears to be more efficient than SIMPLE.
