COMPARISON OF THE FINITE ELEMENT/CONTROL VOLUME METHOD WITH FLOW ANALYSIS NETWORK TECHNOLOGY IN MOULD-FILLING SIMULATION OF RTM PROCESS

The differences between the finite element/control volume method(FE／CVM) and the algorithm of flow analysis network(FAN) technology were analyzed. The results show that the two algorithms based on the triangular grid are uniform and the flow analysis network technology can construct more accurate schemes to calculate the flow rate through the control volume surface in comparison with the conventional finite element/control volume method. Numerical examples show that the accuracy predicted by the flow analysis network technology is several times higher than that predicted by the conventional finite element/control volume method.
