Modeling of flows in a microchannel based on the boltzmann lattice equation

An approach to the analysis of micro- and macroflows with the use of the method of Boltzmann lattices is considered. The velocity profiles of flows in the entry sections of microchannels under no-slip and slip conditions on the wall have been obtained. The influence of the Knudsen number on the hydr...

Zusammenfassung:An approach to the analysis of micro- and macroflows with the use of the method of Boltzmann lattices is considered. The velocity profiles of flows in the entry sections of microchannels under no-slip and slip conditions on the wall have been obtained. The influence of the Knudsen number on the hydrodynamic entrance length of a microchannel and its hydrodynamical resistance have been analyzed.
