ANALYTICAL SOLUTION OF THE VISCOELASTIC MAXWELL EQUATIONS WITH A CRITICAL POINT IN CYLINDRICAL GEOMETRY

This paper examines two-dimensional flows near a free critical point of an incompressible viscoelastic Maxwell medium using the Johnson-Segalman convected derivative. The flow is assumed to be axisymmetric, and its velocity profile is linear along the axial coordinate. A general exact analytical solution is found for the problem of the distribution of the stress tensor components near the stagnation point.
