基金项目: * 国家自然科学基金资助项目

摘要: 本文采用罚-杂交/混合有限元列式,并引用由粘度加权的连续方程的另一种摄动,建议了一种新的粘性不可压幂律流体流动分析的有限元法.提出了一个数值算例,以显示方法的有效性.

Abstract: In this paper, a new finite element method for the flow analysis of the viscous incompressible power-law fluid is proposed by the use of penalty-hybrid/mixed finite element formulation and by the introduction of an alternative perturbation, which is weighted by viscosity, of the continuity equation. A numerical example is presented to exhibit the efficiency of the method.
