Efficacy of reduced order source terms for a coupled wave-circulation model in the Gulf of Mexico
Mark Loveland, Jessica Meixner, Eirik Valseth +1
During hurricanes, coupled wave-circulation models are critical tools for public safety. The standard approach is to use a high fidelity circulation model coupled with a wave model…
Low-dimensional representation of intermittent geophysical turbulence with High-Order Statistics-informed Neural Networks (H-SiNN)
Raffaello Foldes, Enrico Camporeale, Raffaele Marino
We present a novel machine learning approach to reduce the dimensionality of state variables in stratified turbulent flows governed by the Navier-Stokes equations in the Boussinesq…
Helicity dynamics, inverse and bi-directional cascades in fluid and MHD turbulence: A brief review
A. Pouquet, D. Rosenberg, J. E. Stawarz +1
We briefly review helicity dynamics, inverse and bi-directional cascades in fluid and magnetohydrodynamic (MHD) turbulence, with an emphasis on the latter. The energy of a turbulen…
Evidence for Bolgiano-Obukhov scaling in rotating stratified turbulence using high-resolution direct numerical simulations
D. Rosenberg, A. Pouquet, R. Marino +1
We report results on rotating stratified turbulence in the absence of forcing, with large-scale isotropic initial conditions, using direct numerical simulations computed on grids o…
Opportunities for use of exact statistical equations
Reginald J. Hill
Exact structure function equations are an efficient means of obtaining asymptotic laws such as inertial range laws, as well as all measurable effects of inhomogeneity and anisotrop…
Length Scales of Acceleration for Locally Isotropic Turbulence
Reginald J. Hill
Length scales are determined that govern the behavior at small separations of the correlations of fluid-particle acceleration, viscous force, and pressure gradient. The length scal…
