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.

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).

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 ...

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.

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.

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.
