### 4.1.6. Curvature Correction for Two-Equation Models

One weakness of the eddy-viscosity models is that these models are insensitive to streamline curvature and system rotation, which play a significant role in many turbulent flows of practical interest. A modification of the turbulence production term is available to sensitize the standard eddy-viscosity models to these effects. For details, see Curvature Correction for Two-Equation Models in the CFX-Solver Theory Guide.
