Non-Unique Solutions in Turbulent Curved Pipe Flow

The mean flow and turbulent statistics obtained from the direct numerical simulation of a fully developed turbulent flow through a curved pipe with circular cross-section are reported. The Reynolds number based on the bulk velocity and the pipe diameter is approximately 5500, the radius of curvature is equal to five pipe diameters. In the cross-section of the pipe a strong secondary motion is observed. It is shown that in the turbulent case multiple time mean solutions of governing equations exist.
