| Abstract: | In order to track the polymer melt front precisely,the Level Set method is used.The controlling mechanism is the Hele-Shaw model.The level set equations are discretized by the fifth order weighted essentially non-oscillatory scheme,and physical quantities are obtained by central difference scheme.The melt front is tracked accurately and the distribution of the pressure is discussed at different times during the injection molding.The results are promising. |
