On the viscoelastic core of a line vortex embedded in a stagnation point flow. (English) Zbl 1079.76008
Summary: We consider the viscoelastic core of a line vortex embedded in a radially inward axisymmetric stagnation point flow for a Maxwell fluid and an Oldroyd B fluid. Velocity, vorticity and stress distributions are calculated and compared with those for Newtonian fluid. It is found that there are pronounced effects of viscoelastic properties on these distributions with respect to those for Newtonian fluid.
