This paper describes a Unified Flow Solver (UFS) for rarefied and continuum gas flows. The
UFS separates the rarefied and continuum flow domains and selects appropriate solvers to …

A modular particle–continuum (MPC) numerical method for steady-state flows is presented
which solves the Navier–Stokes equations in regions of near-equilibrium and uses the direct …

We propose a direct arbitrary Lagrangian-Eulerian (ALE) variant of the previously developed
discrete velocity method to solve the kinetic equation with the Bhatnagar–Gross–Krook …

The paper is devoted to the development of an efficient deterministic framework for
modelling of three-dimensional rarefied gas flows on the basis of the numerical solution of …

This paper describes an Adaptive Mesh and Algorithm Refinement (AMAR) methodology for
multi-scale simulations of gas flows and the challenges associated with extending this …

HALL thrusters operate through the plasmadynamic interactions of applied electric and
magnetic fields with injected propellant and electrons from a cathode. The advantages of …

ALUNAR spacecraft lands with a gradual powered-descent approach [1], its thruster rocket
nozzle or multiple engine clusters being directed towards the surface of the moon. Because …

Currently the Boltzmann equation and its model equations are widely used in numerical
predictions for dilute gas flows. The nonlinear integro-differential Boltzmann equation is the …

Abstract The high-order Runge–Kutta Discontinuous Galerkin (RKDG) method is applied to
solve the 2D Boltzmann kinetic equations. A conservative DG type discretization of the non …

The problem of rarefied gas flow into vacuum through a short circular pipe is studied
numerically by solving the Boltzmann kinetic equation. Comparison of the results obtained …
