Abstract Aimed at the limitation of the numerical simulation of resin transfer molding processes based on the Darcy law, the resin flow in the fiber preform was modeled as a two-phase (resin and air) fluid flow in porous media. The momentum equations considering the inertia and viscous terms were discretized by the finite volume method (FVM). Combining the FVM with the volume of fluid/piecewise linear interface construction (VOF/PLIC) approach, a new numerical simulation algorithm was presented to solve the transient flow problem, and then a numerical simulation program of the mold filling process was developed. There is a good agreement between the numerical results and the analytical solutions as well as experimental results, so the reliability of the new numerical simulation algorithm is validated.
