A system of model equations is given to describe fully developed turbulent flow with significant curvature of the mean flow streamlines. A feature of the equations is the presence of a gyroscopic stability term to allow for the generation or decay of turbulent energy according as rotation and mean vorticity are anti-parallel or parallel.The Reynolds stresses predicted by the model are realizable. The equations are solved and results presented for turbulent flow between concentric rotating cylinders and the isolated turbulent line vortex. Comparison with experiment is generally favorable.
