Boundary-driven nonequilibrium gas flow in a grooved channel via kinetic theory
(2007)The nonequilibrium flow of a gas in a two-dimensional grooved channel, due to the motion of the wall of the channel, is investigated based on kinetic theory. The presence of the rectangular grooves that are placed periodically ... -
A dissipative particle dynamics study of flow in periodically grooved nanochannels
(2012)The effect of periodic rectangular wall roughness on planar nanochannel flow is investigated by dissipative particle dynamics simulation. The wall protrusion length is varied, and its effect on the flow is examined. Analysis ... -
Effects of wall roughness on flow in nanochannels
(2009)Nonequilibrium molecular dynamics simulation is applied to investigate the effect of periodic wall roughness on the flow of liquid argon through krypton nanochannels. The effect of the length of a rectangular protrusion ... -
Hybrid modeling of time-dependent rarefied gas expansion
(2014)The time evolution of the flow parameters in a system where gas is expanded from a high pressure chamber through a tube toward a low pressure chamber is investigated. During the process, the pressure in the two chambers ... -
A novel experimental setup for gas microflows
(2010)A new experimental setup for flow rate measurement of gases through microsystems is presented. Its principle is based on two complementary techniques, called droplet tracking method and constant-volume method. Experimental ... -
Rarefied gas flow of binary mixtures through long channels with triangular and trapezoidal cross sections
(2010)The flow of binary gas mixtures through long micro-channels with triangular and trapezoidal cross sections is investigated in the whole range of the Knudsen number. The flow is driven by pressure and concentration gradients. ... -
Rarefied gas flow through a cylindrical tube due to a small pressure difference
(2013)Flow of a rarefied gas through a cylindrical tube connecting two reservoirs maintained at a small pressure difference is considered using the axisymmetric version of the linearised BGK kinetic model equation subject to ...
