Impact of Stagnation Temperature and Nozzle Configuration on Rarefied Jet Plume Interactions [PDF]
Journal of Spacecraft and Rockets, 2022 The canting axis of thrusters on space platforms, which likely operate in a vacuum environment with a high degree of flow rarefaction, is significant in order to create the desired torque for manoeuvring, maintaining orbit, eliminating perturbation forces, docking, etc.

Experimental Study on Critical Flow of Supercritical CO2 at Steady State and Model Verification
Yuanzineng kexue jishu, 2022 When the loss of coolant accident happens in a reactor, because of the high temperature and high pressure in the reactor and the low external pressure, the critical flow may occur at the break due to sharp depressurization and vaporization.
