Abstract: An experimental investigation is performed in the present study to identify how can the porous medium behave inside a closed curvy porous cavity heated from below and compare the obtained results with the same numerical simulation model. The numerical model is simulated by ANSYS-CFX R15.0 under Darcy-Forchheimer model with neglecting the viscous dissipation. The work contains also measuring experimentally the permeability of the sand-silica which represents the solid matrix of the porous medium by using a special device made locally. The isotherms form and the temperature distribution on the interior sides of the walls are what explored in this experimental work. The final result leads to an acceptable convergence between these two models (numerical and experimental models). Also, the work gives a proof of the legality of Kozeny-Karman equation to estimate the permeability of the porous medium mathematically.
