Multiscale models, such as the Eddy-Damped Quasi-Normal Markovian one (EDQNM), have been specifically adapted for including rotation, and are consistent with wave-turbulence theory. Being spectral, they assume statistical homogeneity of turbulence. However, turbulence is never really unbounded and homogeneous and the effects of confinement and the consequent lack of homogeneity are usually important. In this talk, we present a numerical implementation of the new wave-turbulence statistical model for rotating turbulence confined in a single direction of rotation developed by Scott (2014). The turbulence is assumed to be statistically homogeneous in unconfined directions parallel to the walls, but confinement means that it is inhomogeneous with respect to the third direction that leads to its discretization in this direction. The velocity field is considered as a combination of inviscid linear inertial waveguide modes.
We will discuss numerical properties of the implementation, it’s parallelization ability as well as the influence of critical points and importance of wall and volumetric damping.
