ABSTRACT

The transient thermal behavior of a homogeneous composite domain described by the hyperbolic heat-conduction model is investigated semianalytically. The composite domain consists of a matrix (fluid domain) and inserts (solid domain), each of which is made of different materials. Two cases are considered. In the first case, the conduction in the solid domain is included and, in the second, the conduction in the fluid domain. The range of parameters, within which the use of the thermal equilibrium assumption in transient flow in porous channel as described by a hyperbolic heat-conduction model, is determined. The effect of different parameters that affect the local thermal equilibrium assumption under the effect of the hyperbolic heat conduction model is also investigated.
