Abstract
Simulation of infrared emission from the exhaust system of an aircraft is of great significance for remote detection and aircraft design. Based on the high-resolution spectral database HITEMP 2010, a narrow band k-distribution (NBK) model is established to calculate radiative properties of hot gases in the plume. Accuracy of the NBK model is validated by comparison with the experimental data and exact line by line (LBL) results. Then the NBK model is coupled with the finite volume method (FVM) to simulate infrared signature of an axis-symmetric nozzle and a two-dimensional nozzle. Infrared radiative properties of these two typical nozzles are calculated and compared. Finally, the outlet sawtooth modifications are applied to the nozzles, the infrared property changes brought about by the trailing edge modifications are analyzed.
