This paper presents an original method for using the commercial code Ansys Fluent for the thermal analysis of microchannel heat sinks based on the porous-medium approach and the local thermal non-equilibrium model. What is new is how heat transfer at the solid porous matrix boundaries is accounted for, because with the original code those boundaries can only be treated as adiabatic. The sample application concerns a double-layered cross-flow microchannel heat sink.

Abstract
This paper presents an original method for using the commercial code Ansys Fluent for the thermal analysis of microchannel heat sinks based on the porous-medium approach and the local thermal non-equilibrium model. What is new is how heat transfer at the solid porous matrix boundaries is accounted for, because with the original code those boundaries can only be treated as adiabatic. The sample application concerns a double-layered cross-flow microchannel heat sink.File in questo prodotto:
