(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. Keyphrases: Darcy-Forchheimer-Brinkman equation, Local Thermal Equilibrium (LTE), mini channel, porous media
