Toward the Simulation of Flashing Cryogenic Liquids by a Fully Compressible Volume of Fluid Solver

We present a fully compressible single-fluid volume of fluid (VOF) solver with phase change for high-speed flows, where the atomization liquid can occur either by aerodynamics or effect local pressure. The VOF approximation among non-miscible (non-condensable gas) and mixture two fluids (liquid vapor) represents core jet its atomization. A barotropic model is used in combination equation state (EoS) to link density pressure temperature. written aim simulate high-pressure injection gas–liquid systems, great enough cause significant compression surrounding gas. Being designed an C++ object-oriented fashion, able support any kind EoS; apply it simulation propellant rocket engines. work includes base development; verification assessment code provided solution set numerical experiments prove boundedness, convergence accuracy method. Experimental measurements cavitating microscopic in-nozzle flow, available literature, are finally first validation change.
