| Abstract: | The reverse Monte-Carlo method was developed to simulate the infrared radiation characteristic of lobed nozzle/mixer plume on the basis of three-dimensional flowfield. The spectral property of plume component was obtained by HITRAN database. Compared with the results gained by standard MonteCarlo method it was showed that the models and the calculating code are correct. The developed method provides an efficient tool for investigating the infrared radiative characteristic of lobed nozzle/mixer plume, and the present results can provide reference for the design of infrared radiation suppression system. |
