Macroscopic continuity, momentum, and energy equations are presented and solved. Local thermal nonequilibrium is considered by means of independent equations for the solid matrix and the working fluid. The used numerical methodology is based on the control-volume approach. The effects of heat generation rate, thermal conductivity ratio, and Biot interstitial number on the local thermal equilibrium are presented. The main results obtained particularly show that lower values of the temperature difference (local thermal equilibrium) between the solid and the fluid phases are obtained at low values of conductivity ratio and high values of Biot number, while large local temperature differences (local thermal nonequilibrium) are obtained for low Biot numbers values and high thermal conductivity ratios. Moreover, increasing heat generation rate generally leads to thermal nonequilibrium accentuation, particularly and most significantly for low Biot number values.
