Solid matrix drag term usually results in a significant pressure drop across the porous medium. The general momentum conservation equation reduces to the extended Darcy's law for the flow in porous media. So Darcy resistance force is very important for the numerical simulation inside the porous media. A new implicit fractional step algorithm is used for the numerical treatment of Darcy drag term and its effect on the residual error of continuity is studied in the present investigation. Faster convergence and reduced mass conservation error is found by using this algorithm.
