Low-Knudsen-number photophoresis of aerosol spheroids [PDF]
Journal of Colloid and Interface Science, 2005 The photophoretic motion of a freely suspended aerosol spheroid exposed to a radiative heat flux that is oriented arbitrarily with respect to its axis of revolution is analytically studied. The Knudsen number is assumed to be so small that the fluid flow can be described by a continuum model with a thermal slip at the particle surface.

Lattice Boltzmann method at finite Knudsen numbers [PDF]
Europhysics Letters (EPL), 2005 A modified lattice Boltzmann model with a stochastic relaxation mechanism mimicking "virtual'' collisions between free-streaming particles and solid walls is introduced. This modified scheme permits to compute plane channel flows in satisfactory agreement with analytical results over a broad spectrum of Knudsen numbers, ranging from the hydrodynamic ...

Inventions, 2023 We are proposing a model mathematical description of droplet evaporation using the kinetic approach. We have obtained the basic equation of the theory by using the law of conserving the full power of the vapor–liquid system, which has not been done ...

Fractional time derivative on fluid flow through horizontal microchannel filled with porous material
International Journal of Aeronautics and Astronautics, 2023 Fractional time derivative is considered in the description of the unsteady fluid flow through a horizontal microchannel filled with porous material. The resultant governing equations were solved using the Laplace transform technique and the method of ...

A wall-function approach to incorporating Knudsen-layer effects in gas micro flow simulations [PDF]
, 2004 For gas flows in microfluidic configurations, the Knudsen layer close to the wall can comprise a substantial part of the entire flow field and has a major effect on quantities such as the mass flow rate through micro devices.

A note on the lattice Boltzmann method beyond the Chapman Enskog limits [PDF]
, 2005 A non-perturbative analysis of the Bhatnagar-Gross-Krook (BGK) model kinetic equation for finite values of the Knudsen number is presented. This analysis indicates why discrete kinetic versions of the BGK equation, and notably the Lattice Boltzmann ...
