Understanding inhomogeneous and anisotropic fluid flows requires mathematical and
computational tools that are tailored to such flows and distinct from methods used to …

Mean-field dynamo theory has important applications in solar physics and galactic
magnetism. We discuss some of the many turbulence effects relevant to the generation of …

The generation of a magnetic field in an electrically conducting fluid generally involves the
complicated nonlinear interaction of flow turbulence, rotation and field. This dynamo process …

Streamwise rolls and accompanying streamwise streaks are ubiquitous in wall-bounded
shear flows, both in natural settings, such as the atmospheric boundary layer, as well as in …

We present direct statistical simulation of jet formation on a β plane, solving for the statistics
of a fluid flow via an expansion in cumulants. Here we compare an expansion truncated at …

Quasilinear theory is often utilized to approximate the dynamics of fluids exhibiting
significant interactions between mean flows and eddies. We present a generalization of …

Zonal flows are well known to arise spontaneously out of turbulence. We show that for
statistically averaged equations of the stochastically forced generalized Hasegawa-Mima …

This paper surveys the basic ideas and results on fundamental models of drift wave
turbulence, the formation of zonal flows, shear suppression of turbulence and transport …

This paper demonstrates the maintenance of self-sustaining turbulence in a restricted
nonlinear (RNL) model of plane Couette flow. The RNL system is derived directly from the …
