Of interest to the research community dealing with real gas flows, this study analyzes the
influence of the physical complexity of real gases on the amplitude of subgrid-scale (SGS) …

In this study, the focus lies on the modeling of the subgrid-scale stress tensor in the context
of real gas flows. By conducting tests on perfect and dense gas configurations using six …

Transcritical turbulent flows are governed by the compressible Navier–Stokes equations
along with a real-gas equation of state. Their computation is strongly susceptible to …

Many turbulent flows are characterized by complex scale interactions and vorticity
generation caused by compressibility and variable-density effects. In the large-eddy …

New subgrid-scale models for the large-eddy simulation of compressible turbulent flows are
developed and tested based on the Favre-filtered equations of motion for an ideal gas. A …

Most sub-grid scale (SGS) models employed in LES (large eddy simulation) formulations
were originally developed for incompressible, single phase, inert flows and assume transfer …

This paper presents a systematic investigation of large eddy simulation (LES) and subgrid
scale (SGS) modeling with application to transcritical and supercritical turbulent mixing and …

A study is conducted to identify advantages and limitations of existing large-eddy simulation
(LES) closures for the subgrid-scale (SGS) kinetic energy using a database of direct …

An a priori study of subgrid-scale (SGS) models for the unclosed terms in the energy
equation is carried out using the flow field obtained from the direct simulation of …

To model the subgrid-scale (SGS) scalar variance under supercritical-pressure conditions,
an equation is first derived for it. This equation is considerably more complex than its …
