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.

A two-pressure model for slightly compressible single phase flow in bi-structured porous media [PDF]
, 2012 Problems involving flow in porous media are ubiquitous in many natural and engineered systems. Mathematical modeling of such systems often relies on homogenization of pore-scale equations and macroscale continuum descriptions.

Multidimensional transonic shock waves and free boundary problems
Bulletin of Mathematical Sciences, 2022 We are concerned with free boundary problems arising from the analysis of multidimensional transonic shock waves for the Euler equations in compressible fluid dynamics.

A Dilating Vortex Particle Method for Compressible Flow with Applications to Aeroacoustics [PDF]
, 2002 Vortex methods have become useful tools for the computation of incompressible fluid flow. In the present work, a vortex particle method for the simulation of unsteady two-dimensional compressible flow is developed and applied to several problems.

Numerical solution of inviscid and viscous laminar and turbulent flow around the airfoil
EPJ Web of Conferences, 2016 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 k-omega model.

Alfvén Instability in a Compressible Flow [PDF]
Physical Review Letters, 2008 A new ideal magnetohydrodynamic instability is presented. It is shown that linear incompressible Alfvénic disturbances can get over-reflected and exponentially amplified in compressible plasma flows. A simple and transparent stability criterion for a two-layer model is derived.

Compressible Flows at Small Reynolds Numbers [PDF]
, 1972 The problem of the slow viscous flow of a gas past a sphere is considered. The fluid cannot be treated incompressible in the limit when the Reynolds number Re, and the Mach number M, tend to zero in such a way that Re ~ o(M^2 ).

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.
