Abstract
We apply inviscid rapid distortion theory to the generalized case of turbulent hyperbolic flow in a
rotating frame and investigate the dependence of the evolution of the turbulent kinetic energy on the
frame rotation rate. We derive an analytical two-dimensional solution which allows for an accurate
approximation of the three-dimensional initially isotropic problem. From the analytical solutions we
determine a new generalized stability criterion for the evolution of the turbulent kinetic energy in
this class of flows
