Engineering Applications of Computational Fluid Mechanics, 2019 The regime of compressible flow generally refers to the super/subsonic case. However, several remarkable cases with low Mach number could not be appropriately described with the incompressible method.

Analytic solutions of a two-fluid hydrodynamic model
Mathematical Modelling and Analysis, 2021 We investigate a one dimensional flow described with the non-compressible coupled Euler and non-compressible Navier-Stokes equations in the Cartesian coordinate system.

The simulation of the flow through the porous media and diffusible barriers
EPJ Web of Conferences, 2018 Here we work with the RANS equations describing the non-stationary viscous compressible fluid flow. We focus on the numerical simulation of the flow through the porous media, characterized by the loss of momentum. Further we simulate the flow through the

Population Genetics in Compressible Flows
Physical Review Letters, 2012 We study competition between two biological species advected by a compressible velocity field. Individuals are treated as discrete Lagrangian particles that reproduce or die in a density-dependent fashion. In the absence of a velocity field and fitness advantage, number fluctuations lead to a coarsening dynamics typical of the stochastic Fisher ...

Two-dimensional compressible viscous flow around a circular cylinder [PDF]
Journal of Fluid Mechanics, 2015 Direct numerical simulation is performed to study compressible viscous flow around a circular cylinder. The present study considers two-dimensional shock-free continuum flow by varying the Reynolds number between 20 and 100 and the free-stream Mach ...

A Compressible Formulation of the One-Fluid Model for Two-Phase Flows
FluidsIn this paper, we introduce a compressible formulation for dealing with 2D/3D compressible interfacial flows. It integrates a monolithic solver to achieve robust velocity–pressure coupling, ensuring precision and stability across diverse fluid flow ...

A Compressible Turbulence Model for Pressure—Strain
Fluids, 2022 This work focuses on the performance and validation of compressible turbulence models for the pressure-strain correlation. Considering the Launder Reece and Rodi (LRR) incompressible model for the pressure-strain correlation, Adumitroaie et al., Huang et

Numerical solution of inviscid and viscous flow around the profile
EPJ Web of Conferences, 2015 This work deals with the 2D numerical solution of inviscid compressible flow and viscous compressible laminar and turbulent flow around the profile. In a case of turbulent flow algebraic Baldwin-Lomax model is used and compared with Wilcox’s k-ω model ...
