Abstract: This paper presents an experimental investigation of how heat release from homogeneous condensation in a supersonic expanding flow affects the density distribution and shock structure of underexpanded rarefied-gas jets. The results demonstrate that this effect is significant for modeling the force and thermal loads imposed by attitude and control thrusters on adjacent spacecraft components.

Keywords: supersonic jets, rarefied gas, homogeneous condensation, gasdynamic structure, clusters.
