This study aims to investigate a computational fluid dynamics (CFD) simulation of a normal and a modified tubular module in order to achieve better filtration performance. The normal module has straight inlet and the modified one has oriented inlet as well as an array of baffles inserted on the module wall. A three-dimensional (3D) method based on the numerical solutions of the Reynolds averaged Navier-Stokes equations was applied for fluid flow in tubular module. A range of local parameters such as stream function, wall shear stress, and velocity upon the membrane surface was evaluated using commercial CFD code FLUENT. It has been observed that modified module creates turbulences higher than normal module. In addition, modified module produces eddy activities which disturb the growth of boundary layer on the membrane surface and enhance the shear force
