Discrete Boltzmann model at Burnett level for compressible multicomponent flows under external forces
Demei Li, Huilin Lai, Chuandong Lin +1
This work extends the Burnett-level discrete Boltzmann model (DBM) from single-component to multicomponent compressible flows under external forces, building on the fundamental fra…
A One-Dimensional Discrete Boltzmann Method for Multidimensional Compressible Flows
Yaofeng Li, Chuandong Lin
A simple and efficient one-dimensional discrete Boltzmann method is developed for compressible flows with tunable specific heat ratios by incorporating extra degrees of freedom. To…
Kinetic study of compressible Rayleigh-Taylor instability with time-varying acceleration
Huilin Lai, Chuandong Lin, Hao Xu +3
Rayleigh-Taylor (RT) instability commonly arises in compressible systems with time-dependent acceleration in practical applications. To capture the complex dynamics of such systems…

Central-moment-based discrete Boltzmann modeling of compressible flows
Chuandong Lin, Xianli Su, Linlin Fei +1
In this work, a central-moment-based discrete Boltzmann method (CDBM) is constructed for fluid flows with variable specific heat ratios. The central kinetic moments are employed to…
Effects of reflection distance on Richtmyer-Meshkov instability in the reshock process: A discrete Boltzmann study
Huilin Lai, Chuandong Lin, Demei Li +4
The Richtmyer-Meshkov (RM) instability occurs when a perturbed interface between two fluids undergoes impulsive acceleration due to a shock wave. In this paper, a numerical investi…
