Aircraft Engine Exhaust Plume Dynamics

Abstract

This report summarizes a research effort to remedy a known deficiency in the Air Quality Assessment Model dispersion calculation capability. Current methods use dispersion calculations and equations for vertical sources (i.e., power plants) resulting in inaccurate assumptions when applied to the horizontal source of an aircraft engine. This study examined the dispersion of aircraft engine exhaust by using infrared thermal imaging techniques. These results were compared to theoretical equations describing jet exhaust plumes. The resulting validation provided the necessary equations and support to mathematically model this phenomena.
