Scattering of swell by currents
Han Wang, Ana B. Villas Bôas, William R. Young +1
The refraction of surface gravity waves by currents leads to spatial modulations in the wave field and, in particular, in the significant wave height. We examine this phenomenon in…
Nusselt number scaling in horizontal convection
Navid C. Constantinou, Cesar B. Rocha, Stefan G. Llewellyn Smith +1
We report a numerical study of horizontal convection (HC) at Prandtl number , with both no-slip and free-slip boundary conditions. We obtain 2D and 3D solutions and determi…
Stokes drift and its discontents
Jacques Vanneste, William R. Young
The Stokes velocity , defined approximately by Stokes (1847, Trans. Camb. Philos. Soc., 8, 441-455), and exactly via the Generalized Lagrangian Mean, is dive…
Interaction of near-inertial waves with an anticyclonic vortex
Hossein A. Kafiabad, Jacques Vanneste, William R. Young
Anticyclonic vortices focus and trap near-inertial waves so that near-inertial energy levels are elevated within the vortex core. Some aspects of this process, including the nonlin…
The Nusselt numbers of horizontal convection
Cesar. B. Rocha, Navid C. Constantinou, Stefan G. Llewellyn Smith +1
We consider the problem of horizontal convection in which non-uniform buoyancy, , is imposed on the top surface of a container and all other surfaces are insulating…
Optimal heat transfer and optimal exit times
Florence Marcotte, Charles R. Doering, Jean-Luc Thiffeault +1
A heat exchanger can be modeled as a closed domain containing an incompressible fluid. The moving fluid has a temperature distribution obeying the advection-diffusion equation, wit…
An asymptotic model for the propagation of oceanic internal tides through quasi-geostrophic flow
Gregory L. Wagner, Gwenael Ferrando, William R. Young
Starting from the hydrostatic Boussinesq equations, we derive a time-averaged `hydrostatic wave equation' that describes the propagation of inertia-gravity internal waves through q…
Refraction of swell by surface currents
Basile Gallet, William R. Young
Using recordings of swell from pitch-and-roll buoys, we have reproduced the classic observations of long-range surface wave propagation originally made by Munk et al. (1963) using…
Mixing by microorganisms in stratified fluids
Gregory L. Wagner, William R. Young, Eric Lauga
We examine the vertical mixing induced by the swimming of microorganisms at low Reynolds and Péclet numbers in a stably stratified ocean, and show that the global contribution of o…
The advection-condensation model and water vapour PDFs
Jai Sukhatme, William R. Young
The statistically steady humidity distribution resulting from an interaction of advection, modeled as an uncorrelated random walk of moist parcels on an isentropic surface, and a v…
Energy-Enstrophy Stability of beta-plane Kolmogorov Flow with Drag
Yue-Kin Tsang, William R. Young
We develop a new nonlinear stability method, the Energy-Enstrophy (EZ) method, that is specialized to two-dimensional hydrodynamics; the method is applied to a beta-plane flow driv…
