3 pagesDate: June 23, 2023

Abstract

The problem of local thermal equilibrium (LTE) between solid and fluid phases in a porous medium is dealt in the present transient numerical study, and, the validity of the LTE is performed for Reynolds no. (10 < Re < 1000) and Darcy no. (10^-6 < Da < 10^0). Observed result shows that, for 100 < Re < 1000, the LTE is valid for all ranges of Da, however, for 10 < Re < 100, the LTE deviates towards non-equilibrium, and the deviation tend to decrease for the lower Da. Time plays a vital role over both the Re and Da.
