Abstract

Ultraviolet OH(A) radiation from the Soyuz-TM spacecraft thruster plume interacting with the ambient gas is calculated at low earth orbit conditions. The direct simulation Monte Carlo method is used in computations. The overlay technique is applied to examine transient flow evolution during first several seconds after motor ignition. Different reaction rates are considered, and the results of computations are compared with the experimental data. The sensitivity of calculated radiation to the molecular collision model is analyzed, and a strong influence of the temperature exponent of the coefficient of viscosity is shown. The contribution of plume near field radiation from CO2 and NO2 is assessed and found to be small compared to that from OH (A). Three-dimensional computations are conducted for different angles between the plume axis and the free stream directions.
