Thermal Transpiration Flow: Molecular Dynamics Study from Dense to Dilute Gas
Thermal transpiration flow, a flow from cold to hot, driven by a temperature gradient along a wall under a high Knudsen number condition, was studied using the molecular dynamics method with a two-dimensional channel consisting of infinite parallel ...

Kinetic theory for a simple modeling of phase transition: Dynamics out of local equilibrium [PDF]
This is a continuation of the previous work (Takata & Noguchi, J. Stat. Phys., 2018) that introduces the presumably simplest model of kinetic theory for phase transition. Here, main concern is to clarify the stability of uniform equilibrium states in the

Analysis of the thermomechanical inconsistency of some extended hydrodynamic models at high Knudsen number [PDF]
There are some hydrodynamic equations that, while their parent kinetic equation satisfies fundamental mechanical properties, appear themselves to violate mechanical or thermodynamic properties.

Incompressible viscous flow near the leading edge of a flat plate admitting slip [PDF]
The shear stress at the leading edge, calculated on basis of the Navier-Stokes equations and the no-slip boundary condition, approaches infinity. However, taking into account the mean free path of the molecules, which implies admitting a certain slip ...

Effects of Slip Boundaries on Mixed Convection of Al2O3-water Nanofluid in Microcavity [PDF]
Due to the importance of the slip effect on modeling of microchannel and microcavity, numerical investigations have been introduced in this work for studying the mixed convection of Al2O3-water nanofluid in a square microcavity.

Acoustic Limit for the Boltzmann equation in Optimal Scaling [PDF]
Based on a recent $L^{2}{-}L^{\infty}$ framework, we establish the acoustic limit of the Boltzmann equation for general collision kernels. The scaling of the fluctuations with respect to Knudsen number is optimal.

A volume-based hydrodynamic approach to sound wave propagation in a monatomic gas [PDF]
We investigate sound wave propagation in a monatomic gas using a volume-based hydrodynamic model. In Physica A vol 387(24) (2008) pp6079-6094, a microscopic volume-based kinetic approach was proposed by analyzing molecular spatial distributions; this led
