Effects of Thermal Stratification on Natural Convection from Heat Source Buried in Porous Medium

Transient and steady natural convection from a heat source embedded in thermally stratified porous layer

“…To validate the numerical code thus developed, it has been tested against the steady-state results published by Prasad and El-Khatib [4]. The present code was able to reproduce the published results and the agreement was excellent as the difference in the maximum stream function and Nusselt number was found to be less than one percent [11]. flow field can also be cross-examined from the propagation of the thermal disturbance caused by the sudden change in the heat source temperature (Fig.…”
