There is few research on fluid force acting on solids and turbulent flow in a pore of porous media because of the difficulty of measurement in experiments. In order to get fundamental knowledge of them, 2-D unidirectional fluid flow is investigated numerically using the Immersed Boundary method, which rigorously satisfies with the boundary condition on the solid surface with Cartesian grid and Lagrangian grid. Calculation results on pressure drop through circular cylinders reasonably agree with experimental formula by Ergun. In addition, fluid force acting on each cylinder, which varies markedly in time and space, is also presented.
