Effect of Aspect Ratio on the Three-Dimensional Global Instability Analysis of Incompressible Open Cavity Flows

, 2011
The stability analysis of open cavity flows is a problem of great interest in the aeronautical industry. This type of flow can appear, for example, in landing gears or auxiliary power unit configurations.

Evolution of an Incompressible Fluid Drop Under a Central Force Field: Analytical Benchmark Solutions for Free‐Surface Flows

Studies in Applied Mathematics, Volume 156, Issue 6, June 2026.
ABSTRACT We present a set of exact and approximate analytical solutions describing the evolution of a fluid drop under the action of a central force field, in both two and three dimensions. The fluid is assumed to be Newtonian and incompressible with a free surface and no solid boundaries The absence of solid walls eliminates boundary‐layer effects ...

Unsteady draining of a fluid from a circular tank

, 2010
Three-dimensional draining flow of a two-fluid system from a circular tank is considered. The two fluids are inviscid and incompressible, and are separated by a sharp interface.

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

A Priori Estimates for Free Boundary Problem of Incompressible Inviscid Magnetohydrodynamic Flows [PDF]

Archive for Rational Mechanics and Analysis, 2013
In the present paper, we prove the a priori estimates of Sobolev norms for a free boundary problem of the incompressible inviscid magnetohydrodynamics equations in all physical spatial dimensions n = 2 and 3 by adopting a geometrical point of view used ...

Distribution, Formation, and Evolution of Subsurface Secondary Acoustic Ducts From Global Ocean Modeling and Observations

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 ...

Short-scale break-up in unsteady interactive layers: Local development of normal pressure gradients and vortex wind-up

, 1998
Following the finite-time collapse of an unsteady interacting boundary layer (step 1), shortened length and time scales are examined here in the near-wall dynamics of transitional-turbulent boundary layers or during dynamic stall.

Motion of a two-dimensional monopolar vortex in bounded rectangular domain [PDF]

, 1996
In this paper we describe results of a study of the two-dimensional motion of a distributed monopolar vortex in a viscous incompressible fluid in a bounded rectangular domain with free-slip and no-slip boundary conditions.

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 balanced approach to modelling rotating stably stratified geophysical flows

, 2003
This work was the first to show how one can rewrite the equations for a rotating stratified fluid in a way which makes potential vorticity conservation explicit.
