In this study, the numerical investigation of the non-linear behavior of the fluid flow with physical properties, such as porosity and
intrinsic permeability of a porous medium, and kinematic viscosity of a fluid, are carried out. The applied numerical model is ANSYS
CFX which is the three-dimensional fluid dynamics model and this model is verified through the application of existing physical and
numerical results. As a result of the verification, the results of the pressure gradient-velocity relationship and the friction coefficient-
Reynolds number relationship produced from this study show relatively good agreement with those from existing physical and numerical
experiments. As a result of the simulation by changing the porosity and intrinsic permeability of a porous medium and the kinematic
viscosity of a fluid, the kinematic viscosity has the biggest effect on the non-linear behavior of the fluid flow in the porous medium.
