Comparative investigation of infrared radiation characteristics of axisymmetrical individual and mixing exhaust systems in turbofan engine
The infrared radiation (IR) characteristics of axisymmetrical individual and mixing exhaust systems in turbofan engine were investigated with the method of numerical simulation.The flow fields of exhaust systems were simulated with commercial software.The IR characteristics were calculated with an IR analysis software based on reverse Monte-carlo method developed by our research group.The IR characteristics in the waveband of 3-5μm of the two exhaust systems and the IR contributions of different solid parts in the nozzles in different detection directions were calculated and analyzed.In the process of IR computation
the emission and reflection of the wall in the nozzle and the absorption and emission of CO2
H2O and CO in the gas jet were considered.The results show that the spatial distribution characteristics of IR of the two exhaust systems are different.The integral IR intensity of the mixing exhaust nozzle is less than that of the individual one except in the azimuth angles of 0° to 10°.
