A volume-of-fluid method for variable-density, two-phase flows at supercritical pressure

J Poblador-Ibanez, WA Sirignano - Physics of Fluids, 2022 - pubs.aip.org
A two-phase, low-Mach-number flow solver is created and verified for variable-density liquid
and gas with phase change. The interface is sharply captured using a split volume-of-fluid …

Temporal atomization of a transcritical liquid n-decane jet into oxygen

J Poblador-Ibanez, WA Sirignano - International Journal of Multiphase Flow, 2022 - Elsevier
The injection of liquid fuel at supercritical pressures is a relevant but overlooked topic in
combustion. Typically, the role of two-phase dynamics is neglected under the assumption …
