ABSTRACT
There is few research on turbulent flow in a pore of porous media and fluid force acting on its components because of the difficulty of measurement in experiments. In this paper, in order to get fundamental knowledge of them, 2-D unidirectional flow passing through circular cylinders was investigated using the Immersed Boundary Method with Physical Virtual Model, which satisfies with the boundary condition on the solid surface with Cartesian fluid grid. Results showed the pressure drop through circular cylinders reasonably agreed with experimental formulas. It was clear that the turbulent transition started from downstream to upstream and it was showed by the analysis of fluid force acting on each cylinder.
