Dynamics of a vortex column of supercritical fluid across the pseudo-boiling line
Jordi Poblador-Ibanez, Fazle Hussain
The evolution of an axisymmetric vortex column in a weakly compressible supercritical fluid is analysed. A thermal layer is imposed to radially stratify the fluid and uncover effec…
A Momentum Balance Correction to the Non-Conservative One-Fluid Formulation in Boiling Flows using Volume-of-Fluid
Jordi Poblador-Ibanez, Nicolas Valle, Bendiks Jan Boersma
A proven methodology to solve multiphase flows is based on the one-fluid formulation of the governing equations, which treats the phase transition across the interface as a single…
Vorticity dynamics in transcritical liquid jet breakup
Jordi Poblador-Ibanez, William Sirignano, Fazle Hussain
Contrary to common assumptions, a transcritical domain exists during the early times of liquid hydrocarbon fuel injection at supercritical pressure. A sharp two-phase interface is…
Temporal atomization of a transcritical liquid n-decane jet into oxygen
Jordi Poblador-Ibanez, William A. Sirignano
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 assumptio…
Liquid-jet instability at high pressures with real-fluid interface thermodynamics
Jordi Poblador-Ibanez, William A. Sirignano
The injection of liquid fuel at supercritical pressures is a relevant topic in combustion, but usually overlooked. In the past, the wrong assumption whereby the liquid experiments…
A Volume-of-Fluid method for variable-density, two-phase flows at supercritical pressure
Jordi Poblador-Ibanez, William A. Sirignano
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-Fl…
Self-similar solution of a supercritical two-phase laminar mixing layer
Jordi Poblador-Ibanez, Branson Davis, William A. Sirignano
Previous works for a liquid suddenly contacting a gas at a supercritical pressure show the coexistence of both phases and the generation of diffusion layers on both sides of the li…
Two-phase developing laminar mixing layer at supercritical pressures
Branson Davis, Jordi Poblador-Ibanez, William A. Sirignano
Numerical analysis of a shear layer between a cool liquid n-decane hydrocarbon and a hot oxygen gas at supercritical pressures shows that a well-defined phase equilibrium can be es…
Transient Behavior near Liquid-Gas Interface at Supercritical Pressure
Jordi Poblador-Ibanez, William A. Sirignano
Numerical heat and mass transfer analysis of a configuration where a cool liquid hydrocarbon is suddenly introduced to a hotter gas at supercritical pressure shows that a well-defi…
