RISEffects of Shear Work on the Non-Equilibrium Heat Transfer Characteristics of Rarefied Micro/Nano Flows
In the current work, the impact of shear work due to the slip velocity on non-equilibrium heat transfer in a pressure driven micro/nanochannel is
evaluated under constant wall heat flux condition. The DSMC method ...
Periodically Patterned Radiometric Pumps: Novel configurations and further application
The current work revisits the radiometric channel pumps [1-2] bounded by various configurations investigating their capacity in gas species separation. Direct simulation Monte Carlo (DSMC) method is successfully employed ...
On the Accuracy of the SBT Collision Algorithm in Nanoflows and Hypersonic Regime
This paper presents a review of the accuracy of the Simplified Bernoulli Trial (SBT) algorithm and its invariants, i.e., SBT-TAS (transient adaptive subcells) and ISBT (intelligence SBT) in the simulation of a wide spectrum of rarefied flow problems...
Knudsen pump inspired by Crookes radiometer with a specular wall
A rarefied gas is considered in a channel consisting of two infinite parallel plates between which
an evenly spaced array of smaller plates is arranged normal to the channel direction. Each of
these smaller ...
