The influence of the temperature term is neglected in the study of lateral jet flows using the momentum analogy method. In this paper, the Reynolds-averaged method is employed for the numerical simulation of the interference flow field caused by lateral jets. The coupling interference mechanism and surface pressure distribution of the rotating body flow field under the influence of temperature terms are comparatively analyzed. The research results indicate that as the total temperature of the jet increases, the pressure coefficient on the upper surface of the rotating body upstream of the nozzle significantly increases, and the differences at other locations are relatively minor. Conversely, when the static temperature rises, the pressure coefficient on the upper surface of the rotating body upstream of the nozzle markedly decreases, with only small variations observed at other positions. The findings of this study can provide references for the refined modeling and analysis of jet interference in engineering applications.
