Homogeneous Turbulent Field within a Rotating Frame

With a view to explaining the behavior of turbulent flows in turbomachine rotors, a turbulent shear flow is examined in a rotating coordinate system. When the turbulent field is homogeneous, equations of second order correlations are written at two points. In order to carry out spectral computations, triple correlations are neglected. Coriolis forces are found to have an effect on the stability of turbulence. Consequences concerning turbulence modeling and applications to turbomachinery are discussed.
