Thermal Equilibrium Assumption For Fluid Flow In Porous Micro-Channel As Described By A Hyperbolic Heat-Conduction Model

Unsteady homogeneous composite domain thermal performance described by the hyperbolic model of heatconduction (HHC) in porous micro-channel is investigated. A solid domain (inserts) and fluid domain (matrix), each made of dissimilar material consists a composite domain,. The parameters range of which the use of the assumption of thermally equilibrium in transient natural convection flow in porous micro-channel which is expressed by a model of HHC is described. Under the existence of the HHC model, several parameters effects on the assumption of local thermal equilibrium (LTE) are investigated. Key words - Heat conduction; composite; porous channel; hyperbolic model; thermal equilibrium assumption.
