Fundamental Study on the Effect of Pore Structure on the Flow through Porous Media by Numerical Calculations
The results of a three-dimensional numerical simulation of the flow through a porous media using the IB method are presented. A series of calculation results show that the flows in the pores and the wake of the porous medium are affected by the Reynolds number and pore structure. It is also shown th...

| description | The results of a three-dimensional numerical simulation of the flow through a porous media using the IB method are presented. A series of calculation results show that the flows in the pores and the wake of the porous medium are affected by the Reynolds number and pore structure. It is also shown that the fluid forces acting on each component sphere differ depending on the porosity and its location in the porous media. The time-varying characteristics of the flow velocity components in the pores of the porous media are also discussed. In addition, the energy drop in the flow direction is shown, and the amount of energy dissipation in the porous media with the different void ratios is compared. Furthermore, the distributions of shear velocity are presented, and the mechanisms of the energy dissipation of the porous media flow are discussed. |
