A discrete Boltzmann model (DBM) is proposed to probe the Rayleigh-Taylor instability (RTI)
in two-component compressible flows. Each species has a flexible specific-heat ratio and is …

The effects of compressibility on Rayleigh-Taylor instability (RTI) are investigated by
inspecting the interplay between thermodynamic and hydrodynamic nonequilibrium …

We present a general framework for constructing trans-scale discrete Boltzmann models
(DBMs) for high-speed compressible flows ranging from continuum to transition regime. This …

In this paper, the coupled Rayleigh–Taylor–Kelvin–Helmholtz instability (RTI, KHI, and
RTKHI, respectively) system is investigated using a multiple-relaxation-time discrete …

In micro-and nanoscale channels, where the characteristic scale approaches or falls below
the mean free path between gas molecules, flow characteristics exhibit pronounced …

The two-dimensional Richtmyer-Meshkov Instability (RMI) system and the coexisting system
combined with Rayleigh-Taylor Instability (RTI) are simulated with a multiple-relaxation time …

A new kinetic model for multiphase flow was presented under the framework of the discrete
Boltzmann method (DBM). Significantly different from the previous DBM, a bottom-up …

Abstract The two-dimensional Rayleigh–Taylor instability problem is simulated with a
multiple-relaxation-time discrete Boltzmann model with a gravity term. Viscosity, heat …

Particle-level simulations of shocked plasmas are carried out to examine kinetic properties
not captured by hydrodynamic models. In particular, molecular dynamics simulations of 2D …
