MULTIPLE RELAXATION TIME LATTICE BOLTZMANN METHOD FOR RAREFIED NANOFLUID FLOW IN TRANSITION REGIME

MULTIPLE RELAXATION TIME LATTICE BOLTZMANN METHOD FOR RAREFIED NANOFLUID FLOW IN TRANSITION REGIME

This work presents a Multiple-Relaxation-Time Lattice Boltzmann Method (MRT-LBM) as an approach to simulate rarefied gas within the transitional regime. Fluid flow in nanochannel is simulated and analysis is carried out. The MRT collision operator is extended to consider the Knudsen number param...
