Theory and computations for breakup of unsteady subsonic or supersonic separating flows [PDF]
, 1994 This study of flow just beyond a breakaway-separation point presents a description of planar nonlinear unsteady effects over a fairly wide parameter range, for a subsonic or supersonic boundary layer at large Reynolds numbers.

Aircraft Wake Vortex Decay in Ground Proximity : Physical Mechanisms and Artificial Enhancement [PDF]
, 2012 Aircraft wake vortex evolution in ground proximity is investigated numerically with large eddy simulations (LES). The simulations are performed with different modifications of the ground surface in order to trigger rapid vortex decay or to simulate the ...

Free Surface Waves in Electrohydrodynamics With a Prescribed Vorticity Distribution
Mathematical Methods in the Applied Sciences, Volume 49, Issue 7, Page 7068-7081, 15 May 2026.ABSTRACT Traditionally, the study of free surface flows assumed irrotationality to simplify matters, and the results seemed to have great success, notably with the Korteweg‐de Vries(KdV) equation. In the past decade, there have been attempts to remove this seemingly strong condition and replace it with a global constant vorticity equivalent to a linear

Fast numerical evaluation of flow fields with vortex cells [PDF]
, 2009 A vortex cell (in this paper) is an aerodynamically shaped cavity in the surface of a body, for example a wing, designed specially to trap the separated vortex within it, thus preventing large-scale unsteady vortex shedding from the wing.

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.Abstract Monthly mean reanalysis from assimilating global ocean circulation models spanning 27 years is used to study subsurface secondary acoustic ducts, which provide waveguides for the transmission of mid‐frequency sound. A systematic diagnosis of secondary ducts from monthly mean temperature and salinity fields characterizes their distribution and ...

Interaction of Ocean Currents and Seamounts: Near‐Bottom Dynamics Around Atlantis II
Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.Abstract This work investigates through a modeling exercise the interaction of a strong, surface current with isolated seamounts, focusing on the Gulf Stream and Atlantis II, one of the New England Seamounts. The roles of bathymetric details and model resolution are investigated with three simulations that consider realistic realizations of the ...

A 'reciprocal' theorem for the prediction of loads on a body moving in an inhomogeneous flow at arbitrary Reynolds number [PDF]
, 2011 Several forms of a theorem providing general expressions for the force and torque acting on a rigid body of arbitrary shape moving in an inhomogeneous incompressible flow at arbitrary Reynolds number are derived.
