The simulation of the gas flow through the porous media and fences [PDF]
EPJ Web of Conferences, 2019 The paper is focused on the numerical simulation of the compressible gas flow through the porous media and fences. We work with the the non-stationary viscous compressible fluid flow, described by the RANS equations.

Modelling compressible multiphase flows [PDF]
ESAIM: Proceedings, 2013 We give in this paper a short review of some recent achievements within the framework of multiphase flow modeling. We focus first on a class of compressible two-phase flow models, detailing closure laws and their main properties. Next we briefly summarize some attempts to model two-phase flows in a porous region, and also a class of compressible three ...

Simplex space‐time meshes in compressible flow simulations [PDF]
International Journal for Numerical Methods in Fluids, 2018 Employing simplex space‐time meshes enlarges the scope of compressible flow simulations. The simultaneous discretization of space and time with simplex elements extends the flexibility of unstructured meshes from space to time.

A Low-Rank Algorithm for Weakly Compressible Flow [PDF]
SIAM Journal on Scientific Computing, 2018 In this paper, we propose a numerical method for solving weakly compressible fluid flow based on a dynamical low-rank projector splitting. The low-rank splitting scheme is applied to the Boltzmann equation with BGK collision term, which results in a set ...

Comparison of dns of compressible and incompressible turbulent droplet-laden heated channel flow with phase transition [PDF]
, 2012 In this paper a turbulent channel flow with dispersed droplets is examined. The dispersed phase is allowed to have phase transition, which leads to heat and mass transfer between the phases, and correspondingly modulates turbulent flow properties.

Linearly Decoupled Energy-Stable Numerical Methods for Multicomponent Two-Phase Compressible Flow [PDF]
SIAM Journal on Numerical Analysis, 2017 In this paper, for the first time we propose two linear, decoupled, energy-stable numerical schemes for multi-component two-phase compressible flow with a realistic equation of state (e.g. Peng-Robinson equation of state).

Smooth transonic flow in an array of counter-rotating vortices [PDF]
, 2005 Numerical solutions to the steady two-dimensional compressible Euler equations corresponding to a compressible analogue of the Mallier & Maslowe (Phys. Fluids, vol. A 5, 1993, p. 1074) vortex are presented.

Population dynamics in compressible flows [PDF]
The European Physical Journal Special Topics, 2012 Organisms often grow, migrate and compete in liquid environments, as well as on solid surfaces. However, relatively little is known about what happens when competing species are mixed and compressed by fluid turbulence. In these lectures we review our recent work on population dynamics and population genetics in compressible velocity fields of one and ...

Compressibility Effects on Cavity Dynamics behind a Two-Dimensional Wedge
Journal of Marine Science and Engineering, 2020 To understand cavity dynamics, many experimental and computational studies have been conducted for many decades. As computational methods, incompressible, isothermal compressible, and fully compressible flow solvers were used for the purpose.
