Simulation of Nonequilibrium Rocket Motor Plumes

Abstract

The research used parallelized computational fluid dynamics methods to make high fidelity simulations of thermo-chemical nonequilibrium flows in rocket motor plumes. This work had two main topics: recent thermal radiative emission experimental data from an Atlas launch were analyzed using a thermo-chemical model with finite-rate internal energy relaxation and chemical reactions. In addition, a detailed analysis of high-temperature flow fields were performed using a vibrational and electronic state-specific excitation model. The simulation results were then used to compute the ultraviolet and infrared radiation emitted from the high-temperature flows to compare with the recent measurements.
