Buoyancy Arrest and Bottom Ekman Transport. Part I: Steady Flow

It is well known that along-isobath flow above a sloping bottom gives rise to cross-isobath Ekman transport and therefore sets up horizontal density gradients if the ocean is stratified. These transports in turn eventually bring the along-isobath bottom velocity, hence bottom stress, to rest (‘‘buoyancy arrest’’) simply by means of the thermal wind shear. This problem is revisited here. A modif...

Steady-state Buoyancy-driven Viscous Flow with Measure Data

Abstract. Steady-state system of equations for incompressible, possibly non-Newtonean of the p-power type, viscous flow coupled with the heat equation is considered in a smooth bounded domain Ω ⊂ n , n = 2 or 3, with heat sources allowed to have a natural L1structure and even to be measures. The existence of a distributional solution is shown by a fixed-point technique for sufficiently small da...

Stratification Effects in a Bottom Ekman Layer

A stratified bottom Ekman layer over a nonsloping, rough surface is studied using a three-dimensional unsteady large eddy simulation to examine the effects of an outer layer stratification on the boundary layer structure. When the flow field is initialized with a linear temperature profile, a three-layer structure develops with a mixed layer near the wall separated from a uniformly stratified o...

Flow-induced wall shear stress in abdominal aortic aneurysms: Part I--steady flow hemodynamics.

Numerical predictions of blood flow patterns and hemodynamic stresses in Abdominal Aortic Aneurysms (AAAs) are performed in a two-aneurysm, axisymmetric, rigid wall model using the spectral element method. Homogeneous, Newtonian blood flow is simulated under steady conditions for the range of Reynolds numbers 10 < or =Re < or =2265. Flow hemodynamics are quantified by calculating the distributi...

Study of Transient Flow and Particle Transport in Continuous Steel Caster Molds: Part I. Fluid Flow

Unsteady three-dimensional flow in the mold region of the liquid pool during continuous casting of steel slabs has been computed using realistic geometries starting from the submerged inlet nozzle. Three largeeddy simulations (LES) have been validated with measurements and used to compare results between full-pool and symmetric half-pool domains and between a full-scale water model and actual b...
