This chapter explores pressure-driven rarefied flows, focusing on Poiseuille flow in micro- and nano-channels. It presents analytical solutions over a broad spectrum of Knudsen numbers, assesses various velocity slip boundary conditions, and delves into heat transfer, wall interactions, and supporting experimental data. The chapter also covers step flow analysis and modeling of porous microchannels.

摘要

This chapter explores pressure-driven rarefied flows, focusing on Poiseuille flow in micro- and nano-channels. It presents analytical solutions over a broad spectrum of Knudsen numbers, assesses various velocity slip boundary conditions, and delves into heat transfer, wall interactions, and supporting experimental data. The chapter also covers step flow analysis and modeling of porous microchannels.
