Physical review. E, Statistical, nonlinear, and soft matter physics

The effective stress tensor of a homogeneous turbulent rotating fluid is anisotropic. This leads us to consider the most general axisymmetric four-rank "viscosity tensor" for a Newtonian fluid and the new terms in the turbulent effective force on large scales that arise from it, in addition to the microscopic viscous force. Some of these terms involve couplings to vorticity and others are angular momentum nonconserving (in the rotating frame). Furthermore, we explore the constraints on the… Expand

The turbulent state of a fluid is characterized by the presence of fluctuations of the velocity in a wide range of scales. These irregular velocity fluctuations enhance the dissipation of energy in… Expand

TLDR

The range of parameters at which the large- scale instability occurs, the growth rate of the instability, and the frequency of the generated large-scale inertial waves are determined.Expand

Under the action of solid body rotation, homogeneous neutrally stratified turbulence undergoes anisotropization and onset of the inverse energy cascade. These processes are investigated using a… Expand

Abstract There is a large body of experimental evidence which shows that the jet noise spectrum is composed of two sources. Our aim here is to prove, mathematically, that the two-source paradigm can… Expand
