Acceleration schemes of the discrete velocity method: Gaseous flows in rectangular microchannels
(2003)The convergence rate of the discrete velocity method (DVM), which has been applied extensively in the area of rarefied gas dynamics, is studied via a Fourier stability analysis. The spectral radius of the continuum form ... -
Application of the integro-moment method to steady-state two-dimensional rarefied gas flows subject to boundary induced discontinuities
(2008)The computational efficiency of the integro-moment method for solving steady-state two-dimensional rarefied gas flows is investigated. The two-dimensional boundary driven flow of a single gas in a cavity is used as a model ... -
Conductive heat transfer in a rarefied polyatomic gas confined between coaxial cylinders
(2014)The conductive heat transfer through rarefied gases composed by rigid rotators and confined between coaxially placed cylinders maintained at different temperatures is investigated on the basis of the Holway and Rykov kinetic ... -
A fast iterative model for discrete velocity calculations on triangular grids
(2010)A fast synthetic type iterative model is proposed to speed up the slow convergence of discrete velocity algorithms for solving linear kinetic equations on triangular lattices. The efficiency of the scheme is verified both ... -
Formulation and stability analysis of rapidly convergent iteration schemes for the 2-D linearized BGK equation
(2007)Various H-N rapidly convergent schemes are proposed to speed up the slow convergence of the iterative solution of 2-D linearized Bhatnagar-Gross-Krook (BGK) kinetic equation containing up to the first moments of the ... -
Rarefied gas flow in concentric annular tube: Estimation of the Poiseuille number and the exact hydraulic diameter
(2008)The fully developed flow of rarefied gases through circular ducts of concentric annular cross sections is solved via kinetic theory. The flow is due to an externally imposed pressure gradient in the longitudinal direction ...
