Approximate Determination of Jet Contours near the Exit of Axially Symmetrical Nozzles as a Basis for Plume Modeling

Abstract

A simple, approximate method is presented for rapid determination (utilizing mini-computers) of plume shapes produced by jet expansion from axially symmetric nozzles. The analysis is based on concepts developed by Johannesen and Meyer. It is shown how the method for plume shape determination can be utilized to model at least the geometric aspects of prototype plumes as well as to account for significant inviscid and viscid aspects of the base flow problem. A calculation procedure and numerical examples are presented to guide the reader in applying the modeling technique.
