Impinging rotational stagnation-point flows

A rotational stagnation-point flow of fluid density ρ1 and kinematic viscosity ν1 impinges normal to another rotational stagnation-point flow of fluid density ρ2 and viscosity ν2. Results are compared with a previous study on the normal impingement of two Homann stagnation-point flows for which the flow in the far field is irrotational.
