The modeling of fluids in the supercritical regime is addressed at conditions characteristic of
liquid-propelled rocket engines, whose increasing performance demands paved the way for …

Low temperatures and high pressure at the nozzle inlet of the thrusters can cause liquid
droplets to form downstream. During this event, the outlet pressure of the nozzle increases …

Three-dimensional large-eddy simulations (LES) of supercritical nitrogen injection are
carried out over a range of swirl numbers (0≤ S< 2) to investigate the characteristics of the …

The trans/supercritical injection of cryogenic fluids is extensively used in practical
applications. However, the corresponding heat transfer and jet turbulence characteristics are …

The new generation of large-thrust rockets commonly employ cryogenic liquids such as
liquid hydrogen (LH2), liquid oxygen (LOX), and methane as propellants. Conventional …

Supercritical nitrogen jet behavior is modeled using an incompressible but variable density
approach developed for variable density jets. Following mechanical and thermal breakup …

The injection of nitrogen under supercritical and transcritical conditions, where the injection
temperature is below nitrogen's critical point, but the pressure is above it, is considered in …
