Abstract
A coupling calculation model for infrared radiation transfer of plume is built. The radiation source term is induced into energy equation, thus the plume flow field and radiation transfer can be solved in couple. A finite rate model is used to simulate the afterburning phenomenon; a discrete coordinate method is used to solve the radiation transfer equation. The spectral radiation intensity from 1000 cm -1 to 4500 cm -1 and the radiation intensity contours are obtained. The calculation results concide well with the experiment data. It shows that the motor's operation pressure, the free stream's Mach number and flight height can change the flow structure and temperature distributions of the plume in a extent.
