Abstract
A numerical scheme for computing the advancement of a flow front and related velocity, pressure, conversion and temperature distributions during mold filling in reaction injection molding (RIM) is described in this work. In the RIM process, the convective term in the energy equation is dominant. Therefore, the numerical scheme has incorporated a Petrov-Galerkin finite element method to suppress spurious oscillations and to improve accuracy of the calculations. The other feature of the numerical scheme is that the flow front locations are computed simultaneously with primary variables by using a surface parameterization technique. The numerical results compare well with the reported experimental data. Improved accuracy obtained by this numerical scheme in the flow front region is expected to assist in the predictions of the fiber orientations and the bubble growth in RIM, which are determined primarily by the flow front region.
