A model is developed for describing mixing of several species under high-pressure
conditions. The model includes the Peng–Robinson equation of state, a full mass-diffusion …

Injection at pressures exceeding the propellant critical pressures is typically considered a
diffuse interface mixing process rather than a sharp interface break-up. However, this is not …

Experiments and simulations were carried out to contribute to a better understanding and
prediction of high-pressure injection into a gaseous environment. Specifically, the focus was …
