On a nonlinearity in flow birefringence

This note presents a general optical relation for three-dimensional birefringent fluids which explains observed cross effects and gives a meaning to isoclinics

Conclusion

The nonlinearity observed in the flow-birefringent data can be explained by considering a properly formulated constitutiv relation, and is seen to be a natural consequence of the representation of a tensor function. The optical relation proposed is valid for a general threedimensional flow and, in addition, gives a meaning to the isoclinics in terms of the strain-rate components.
