用流体双折射的位相差积分法定量分析具有对称平面的三维流场

PHASE RETARD INTEGRATION METHOD USED IN FLOW BIREFRINGENCE TO ANALYSE THE FLOW WITH A SYMMETRIC PLANE

摘要: 本文对流体双折射方法做了简单的回顾。用位相差积分理论导出了具有对称平面双折射介质所适用的公式。作为实例,我们定量分析了扩张和收缩管中的剪应变率分布。

Abstract: The formulas which can be used for birefringent medium with a symmetric plane are derived by means of phase retard integration. Axisymmetric problems are studied and some useful formulas are obtained for these cases. As a practical application, the strain rate analyses of flow in a diverging vessel and a converging vessel have been made at the end of this paper
