Utilizing phase retard integration method of flow birefringence to analyse the flow with symmetric plane

The formulas which are suitable to birefringent medium with symmetric plane are derived by means of phase retard integration. We have adopted this concept to the axisymmetric problems and deduced some useful formulas for these cases. As a practical application, the strain rate analysis of flow in a diverging or a converging vessel is illustrated at the end of this paper.
