When discussing research in physics and in science more generally, it is common to ascribe
equal importance to the three components of the scientific trinity: theoretical, experimental …

For the last several decades, renormalization group (RG, or RNG) methods have been
applied to a wide variety of problems of turbulence in hydrodynamics and plasma physics. A …

Two decades ago when we wrote Spectral Methods in Fluid Dynamics (1988), the subject
was still fairly novel. Motivated by the many favorable comments we have received and the …

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 …

The role of mesoscale oceanic eddies in driving large-scale currents is studied in an eddy-
resolving midlatitude double-gyre ocean model. The reference solution is decomposed into …

The focus of this paper is to perform coarse-grid large-eddy simulation (LES) using recently
developed sub-grid scale (SGS) models of cylinder wake flow at Reynolds number (Re) of …

We explore the potential of a formulation of the Navier-Stokes equations incorporating a
random description of the small-scale velocity component. This model, established from a …

Planetary turbulent flows are observed to self-organize into large-scale structures such as
zonal jets and coherent vortices. One of the simplest models of planetary turbulence is …

We introduce a novel way to extract information from turbulent datasets by applying an Auto
Regressive Moving Average (ARMA) statistical analysis. Such analysis goes well beyond …

Nonlinear rectification of the ocean circulation driven by random forcing, which simulates the
effect of unresolved eddies, is studied in an idealized closed basin. The results are based on …
