An Improved Method of Numerical Simulation of Resin Transfer Molding for Resin-Based Composite Materials Based on Unstructured Grid

摘要

The authors have a lot researches about numerical simulation of resin transfer molding for resin-based composite materials based on unstructured grid in the past. In these researches the authors found while the grid is orthogonal, the simulation is agreed with facts. But the grid is non-orthogonal, the energy equation has great error due to being simplified, and the results are wrong. The mesh distortion is larger, the deviations are bigger. Therefore, this paper conducted a study about the calculation methods of the energy equation, and validated through case reasonableness and accuracy of the calculation method. The results show the improvement is effective.
