RISTwo relaxation time lattice Boltzmann equation for high Knudsen number flows using wall function approach
In the present study, we investigate gas flow in a micro-/nanochannel by using the two relaxation time lattice Boltzmann equation (TRT-LBE). The wall function approach is employed in order to consider the effect of Knudsen layer in transition flow...
A new calculation method for thermal and electical characterization in CdTe and CdSe semiconductors
A new calculation method has been developed and used to model electron transport properties in
semiconductor devices under thermal and electrical applications. Using the relaxation-time
approximation, the ...
Comparison of electron-plasmon scattering effect on low-field electron mobility in ZnO and SiC
Iterative technique is used to solve Boltzmann transport equation for calculating temperature and
doping dependencies of electron mobility in ZnO and SiC materials. The two-mode nature of the polar

Simulation of Rarefied Gas Flow in Micro/Nano Cavity Using DSMC
Direct simulation Mont Carlo (DSMC) is a molecular
approach which is widely used to model rarefied gas
flow in a wide range of Knudsen numbers. Lid-driven
cavity is a common geometry used in ...
Detailed Investigation of Rarefied Flow in Micro/Nano Lid-driven Cavities Using DSMC
We use DSMC technique to investigate hydrodynamic

micro/nano lid-driven cavity. Flow behavior in all
rarefaction regimes including slip, transition ...
Calculation of the electron drift mobility in Cr2+:ZnS and Cr2+:ZnSe materials by rode iteration model

The Boltzmann equation is solved by an iterative technique using the currently established values of
the material parameters. The iterative results are in fair agreement with other recent calculations...
Two relaxation time lattice Boltzmann model for rarefied gas flows
In this paper, the lattice Boltzmann equation (LBE) with two
relaxation times (TRT) is implemented in order to study gaseous flow
through a long micro/nano-channel. A new relation is introduced for the
reflection factor...
Lattice Boltzmann Finite Volume Formulation with Improved Stability
The most severe limitation of the standard Lattice Boltzmann Method is the
use of uniformCartesian grids especiallywhen there is a need for high resolutions near
the body or thewalls. Among the recent advances ...
A THOROUGH EVALUATION OF THE FOKKER-PLANCK KINETIC MODEL IN THE COUETTE FLOW
In this paper, the evolution of Fokker-Planck (FP) approach in various Knudsen numbers and number of particles per cells (PPC) was investigated. A canonical argon Couette flow has been chosen. However, there are some other ...
Pressure-driven electrokinetic slip-flow in planar microchannels
with the Poissone Boltzmann equation for the electric double layer. Analytical
expressions for the velocity profile, average electrical conductivity, and induced voltage are presented
without invoking the DebyeeHückel approximation. It is known...
