It is well established that dimples accelerate the drag crisis on a sphere. The result of the early drag crisis is a reduction of the drag coefficient by more than a factor of two when compared to a smooth sphere at the same Reynolds number. However,

SynopsisThe fluid dynamics of owls in flapping flight is studied by coordinated experiments and computations. The great horned owl was selected, which is nocturnal, stealthy, and relatively large sized raptor. On the experimental side, perch-to-perch

In the present work the effects of different types of roughness elements on flow separation over a circular bump is investigated by means of direct numerical simulations. Two types of roughness elements are considered, dimples and spherical beads. Th

We studied left ventricular flow patterns for a range of rotational orientations of a bileaflet mechanical heart valve (MHV) implanted in the mitral position of an elastic model of a beating left ventricle (LV). The valve was rotated through 3 angula

A series of direct numerical simulations of the flow past a flat plate with two and eight rows of dimples in a staggered arrangement is carried out. The Reynolds number based on the boundary layer thickness and freestream velocity near the inflow pla

Modeling a dilute suspension of particles in a polykinetic Eulerian framework is described using the conditional quadrature method of moments (CQMOM). The particular regimes of interest are multiphase flows comprised of particles with diameters small

Detached-eddy simulation (DES) is applied to prediction of the super-critical flow around a circular cylinder. One of the primary aims is to assess a new DES version developed by Spalart et al. [2006. A new version of detached-eddy simulation, resist

Predictions of the massively separated flow around a rectangular ogive forebody are obtained using detached-eddy simulation and from a solution of the unsteady Reynolds-averaged Navier-Stokes equations. The lengths of the forebody and aftbody are 2 a

CO2 sequestration via carbonation of widely available low-cost minerals, such as olivine, can permanently dispose of CO2 in an environmentally benign and a geologically stable form. We report the results of studies of the mechanisms that limit aqueou

Detached-eddy simulation (DES) is well understood in thin boundary layers, with the turbulence model in its Reynolds-averaged Navier–Stokes (RANS) mode and flattened grid cells, and in regions of massive separation, with the turbulence model in its
