• The problem of viscous flow near a stagnation point has been exactly solved by Froessling. In this paper equations of motion for the flow of a visco-elastic liquid near a stagnation point, occurring when a stream of such a liquid impinges on a wall at right angles to it and flows away radially in all directions, have been set up and solved by the Karman-Pohlhausen method. The effect of elasticity is found to depend upon a non-dimensional parameter τ^* = Tα (where τ is the flow parameter or the relaxation time constant and α is a constant of dimensions T^<-1> depending on the velocity in potential flow). Behaviour for small values of this parameter has been studied. It is observed that the boundary layer thickness and the shearing at the wall increase with an increase in τ^*, while the normal stress at the wall is independent of both elasticity and viscosity. The stream lines get closer to the wall with an increase in the parameter. and dot denotes the rate of change.
