Numerical simulation of the resin transfer mold filling process using the boundary element method

摘要: A numerical simulation of the mold filling process during resin transfer molding with a heated die was performed using boundary element method. The governing differential equation variable coefficient rearranged into system Poisson equations perturbation technique. method employed to solve resulting equations. viscosity calculated by introducing markers at inlet and tracing them. As calculation domain changes because proceeding front, nodes on were for each time step integration only meshes in among fixed over mold. Sample calculations two molds different shapes. To check validity scheme, mass flow rate front compared flux inlet. Close agreement observed.
