摘      要：In this paper a constitutive equation for the extra stress tensor tau is considered, which can be used for steady axisymmetric flows when mu(phi)=0 (non-swirling). It is explicit with coefficients which, in case of incompressibility, depend only upon three invariants. As such it should prove useful in numerical calculations, especially so if used in its simplest form, namely the quasi-Newtonian fluid Here, a purely viscous code can be used. The constitutive equation is self-consistent and receives additional justification from the fact that any constitutive equation is bound to result in the form proposed if the flow is a constant stretch history flow.
