Special Issue on Recent Hot Topics in Rarefied Gas Dynamics [PDF]
, 2021 Rarefied gas flows are present in a wide range of scientific and technological problems, such as hypersonic vehicles flying at very high altitudes, propulsion systems of spacecraft navigating in space, and vacuum devices operating on the ground.

On the modelling of isothermal gas flows at the microscale [PDF]
, 2008 This paper makes two new propositions regarding the modelling of rarefied (non-equilibrium) isothermal gas flows at the microscale. The first is a new test case for benchmarking high-order, or extended, hydrodynamic models for these flows.

Physical Review Accelerators and Beams, 2021 A transverse beam profile monitor that visualizes a two-dimensional beam-induced fluorescent image was developed. The monitor employs a sheet-shaped gas flow formed by a technique of rarefied gas dynamics.

Asymptotic Theory of Rayleigh Problem in Rarefied Gas [PDF]
, 1979 The asymptotic theory of Rayleigh shear flow for large values of time is developed on the basis of the linearized Boltzmann-Krook equation. Asymptotic equations for mean velocity outside the Knudsen layer are obtained by employing the Hilbert expansion ...

The effect of system boundaries on the mean free path for confined gases
AIP Advances, 2013 The mean free path of rarefied gases is accurately determined using Molecular Dynamics simulations. The simulations are carried out on isothermal argon gas (Lennard-Jones fluid) over a range of rarefaction levels under various confinements (unbounded gas,

On the accuracy of macroscopic equations for linearized rarefied gas flows
Advances in Aerodynamics, 2020 Many macroscopic equations are proposed to describe the rarefied gas dynamics beyond the Navier-Stokes level, either from the mesoscopic Boltzmann equation or some physical arguments, including (i) Burnett, Woods, super-Burnett, augmented Burnett ...

Study of the coupling between real gas effects and rarefied effects on hypersonic aerodynamics [PDF]
, 2012 Hypersonic vehicles travel across the atmosphere at very high speed, and the surrounding gas experiences complicated physical and chemical processes. These processes produce real gas effects at high temperature and rarefied gas effects at high altitude ...

Nearly Free Molecular Heat Transfer from a Sphere [PDF]
, 1968 Consider a sphere immersed in a rarefied monatomic gas with zero mean flow. The distribution function of the molecules at infinity is chosen to be a Maxwellian. The boundary condition at the body is diffuse reflection with perfect accommodation to the

Evaporation Boundary Conditions for the Linear R13 Equations Based on the Onsager Theory
Entropy, 2018 Due to the failure of the continuum hypothesis for higher Knudsen numbers, rarefied gases and microflows of gases are particularly difficult to model.
