Infrared radiation suppression of wake flow with carbon particles group is one of the important subjects of infrared stealth technology. Based on the platform of computational fluid dynamics software Fluent,numerical simula-tion of infrared radiation suppression of wake flow of propeller airplane with carbon particles has been carried out. In-frared radiation translation is calculated by ray-tracing method. By comparing the intensity of infrared radiation,laws of jet velocity and injection quantity of the particles which are suitable for this type of propeller airplane are obtained, which can provide references for carrying out experimental research and program design.
