Assessment of Turbulence-Chemistry Interactions in Missile Exhaust Plume Signature Analysis

Abstract

The combustion or afterburning of fuel-rich rocket exhaust with the atmosphere may result in large infrared radiation emissions which can play a significant role in the design of missile base components and missile defense systems. Current engineering level models neglect turbulence chemistry interactions and typically underpredict the intensity of plume afterburning and afterburning burnout. To evaluate the impact of turbulence-chemistry interactions, an assumed pdf model was applied to missile plume simulations of a generic booster. Simulation results reveal turbulence chemistry interactions to have a large impact on plume signatures as afterburning burnout was approached.
