The viscoelastic flow from a tube into a radial slit between two parallel disks is investigated numerically by orthogonal collocation. A modified ZFD model and a generalized Newtonian fluid, with identical viscosity functions, are investigated. Results for these models indicate that fluid elasticity alters the velocity profiles significantly, but has little effect on the pressure profile in the radial flow region.
