摘要：
分析了不可压缩、非等温、黏性非牛顿流体在型腔内的流动特点，应用小波有限元法准确地模拟出熔体型腔内充模流动模型，克服了传统有限元在工程奇异性问题求解中的不足。算例表明，数值计算结果与实验结果比较一致，该方法成功地模拟了注塑成形型腔内流体的流动过程的重要特征。
关键词: 流动模型；小波有限元；奇异性；数值计算
Abstract:
The flowing characteristics of incompressible nonisothermal viscous non-Newtonian fluids in mold cavity was analysed.The model of the mold cavity was accurately simulated with the application of wavelet finite element method,this method overcome the deficiency in engineering singularity of the traditional finite element method.The numerical calculation result is in concordance with experiment,and this method successfully simulates the important features of the flowing process in mold cavity.
Key words: flowing model;wavelet finite element method;singularity;numerical calculation
