Die räumliche Staupunktströmung für ein viskoelastisches Fluid. (Spatial stagnation point flow of a viscoelastic fluid). (German) Zbl 0626.76011
In this paper the flow of a Rivlin-Ericksen fluid near an axisymmetric stagnation point is investigated. Using a similarity transformation one gets a fourth-order differential equation for the dimensionless stream function. It is shown that nevertheless the usual three boundary conditions are sufficient. Velocity profiles are calculated for various combinations of the interesting parameters. Finally the wall shear stress is calculated.
