The code is validated by using experimental results. Results indicated that the heat transfer coefficient of the moving porous moist object is time dependent and varying locally.

Porosity is the property of an object that expresses the total volume of empty or pore space in the material. For rocks that contain hydrocarbon resources, porosity measures the percentage pore space occupies in a rock. [2] A porous rock contains a large number of tiny spaces, which allows it to hold oil, natural gas or even underground water! [3]

In the past few decades, considerable research efforts in porous object design have been reported [1, 3-13].
