Fluid flow in porous media has many applications in various engineering fields such as filtration and purification processes, geological studies and petroleum industry, etc. This final assignment discusses multiphase fluid flow in porous media, the aim to be achieved is to determine the influence of the mesh on simulation results, flow velocity in branched pipes, and the speed of bubbles formed. Fluid flow will be simulated using the OpenFoam program, the method used in this program is the Finite Volume Method. Then, for the results and discussion, we will first simulate the multiphase poiseuille flow of water pushing oil in a cylindrical pipe. After that, the flow will be simulated in a pipe that branches into 3 smaller pipes, we will see the influence of the selected mesh, and also the bubbles and flow that form in the branching pipes. The conclusion of this research is that the pressure gradient of the poiseuille flow decreases linearly towards zero and the velocity profile obtained is parabolic. The choice of mesh greatly influences the simulation results, then the flow speed is fastest in the tube branch with the largest diameter, then the initial pressure is directly proportional to the overall flow speed. The capillary effect causes bubbles to prefer to pass through larger pipe branches.
