Abstract:The pressure and temperature distributions on the surface of a model of serpentine two-dimensional(2-D)nozzle exhaust system were measured, and its infrared radiation(IR) intensity on the side, lower and upper detection planes were also measured; these results were compared with those of a relevant axisymmetric exhaust system. The results showed that, the radiation intensity of serpentine 2-D nozzle exhaust system on the upper detection plane was much higher than that on other two planes, with the maximum value at angle 10°; compared with axisymmetric exhaust system, the radiation intensity of serpentine 2-D nozzle exhaust system reduced by 75.5% at angle 0°, and 57.6%, 50.9% and 17.3% at angle 90° respectively on the side, lower and upper detection planes. © 2017, Editorial Department of Journal of Aerospace Power.
