Abstract:
Provided is a method of calculating a tortuous hydraulic diameter of a porous medium for laminar flow and turbulent flow considering a geometric feature and a friction loss feature. A method of calculating a tortuous hydraulic diameter of a porous medium, according to an embodiment of the present invention, includes providing porosity and a specific surface area of a porous medium, calculating a hydraulic diameter of the porous medium by using the porosity and the specific surface area, calculating tortuosity of the porous medium, and calculating a tortuous hydraulic diameter corresponding to a function of tortuosity, by using the hydraulic diameter and the tortuosity of the porous medium.
