Abstract:
The entropy generation for steady, compressible gas flow inside two-dimensional rectangular microchannel at slip flow regime with constant walls temperature has been investigated. The obtained solutions of the flow field are used to evaluate the entropy generation, Bejan number and irreversibility ratio inside the microchannel. Finally, the influence of Knudsen number, Brinkman number, aspect ratio, and pressure ratio on entropy generation rate and irreversibility were presented.
