中文摘要	in resin transfer molding processes, the edge effect caused by the nonuniformity of permeability between fiber preform and edge channel may disrupt resin flow patterns and often results in the incomplete wetting of fiber preform, the formation of dry spots, and other defects in final composite materials. so a numerical simulation algorithm is developed to analyze the complex mold-filling process with edge effect. the newly modified governing equations involving the effect of mold cavity thickness on flow patterns and the volume-averaging momentum equations containing viscous and inertia terms are adopted to describe the fluid flow in the edge area and in the fiber preform, respectively. the volume of fluid (vof) method is applied to tracking the free interface between the two types of fluids, namely the resin and the air. under constant pressure injection conditions, the effects of transverse permeability, edge channel width, and mold cavity thickness on flow patterns are analyzed. the results demonstrate that the transverse flow is not only affected by the transverse permeability and the edge channel width but also by the mold cavity thickness. the simulated results are in agreement with the experimental results.
