  journal={arXiv: Fluid Dynamics},
Numerical analysis of a shear layer between a cool liquid hydrocarbon and a hotter oxygen gas at supercritical pressures shows that a well-defined phase equilibrium can be established. Variable properties are considered with the product of density and viscosity in the gas phase showing a nearly constant result. Sufficiently thick diffusion layers form around the liquid-gas interface for the selected free-stream velocities at a streamwise distance of x = 1 cm for different pressures (i.e., 10…

On the transition between two-phase and single-phase interface dynamics in multicomponent fluids at supercritical pressures
A theory that explains the operating pressures where liquid injection processes transition from exhibiting classical two-phase spray atomization phenomena to single-phase diffusion-dominated mixing
Subcritical to supercritical mixing
Liquid jet injection into a quiescent gaseous environment has been experimentally and analytically studied covering subcritical to supercritical conditions. The focus was placed on the influence that
Planar liquid jet: Early deformation and atomization cascades
The temporal evolution of three-dimensional instabilities on a planar liquid sheet segment is studied using direct numerical simulation, and the level-set and volume-of-fluid methods for the
Vorticity dynamics for transient high-pressure liquid injectiona)
The liquid jet from a round orifice during the transient start-up and steady mass flux periods of a high pressure injector is studied via Navier-Stokes and level-set computations. Via
Injection and Mixing Processes in High-Pressure Liquid Oxygen/Gaseous Hydrogen Rocket Combustors
The injection, mixing combustion processes in a liquid oxygen (LOX)/gaseous hydrogen (GH2) rocket engine combustor at high chamber pressures (10 MPa) are studied and modeled. An experimental LOX/GH2
