This is an attempt to clarify and size up the many levels possible for the numerical prediction
of a turbulent flow, the target being a complete airplane, turbine, or car. Not all the author's …

The flow is calculated with laminar separation (LS) at Reynolds numbers 50,000 and
140,000, and with turbulent separation (TS) at140, 000 and 3× 10 6. The TS cases are …

In this study we investigate the onset of three-dimensionality in an otherwise two-
dimensional periodic wake of a square cylinder. Floquet stability analysis is employed to …

We investigate numerically vortex-induced vibrations (VIV) of two identical two-dimensional
elastically mounted cylinders in tandem in the proximity–wake interference regime at …

The flow field around a sphere in an uniform flow has been analyzed numerically for
conditions corresponding to the subcritical (laminar separation) and supercritical (turbulent …

The presence of low-frequency fluctuations in the wake of bluff bodies have been observed
in several investigations. Even though the flow past a circular cylinder at Re= 3900 (Re= U …

While the wake of a circular cylinder and, to a lesser extent, the normal flat plate have been
studied in considerable detail, the wakes of elliptic cylinders have not received similar …

This study numerically investigates the time-resolved laminar flow over rectangular cylinders
with cross-sectional aspect ratio Ar varying from square cylinder (Ar= 1) to normal flat plate …

The spatio-temporal dynamics of separation bubbles induced to form in a fully developed
turbulent boundary layer (with Reynolds number based on momentum thickness of the …

To draw a precise picture of the hierarchy of coherent vortices in spatially periodic
turbulence at high Reynolds numbers and to understand its generation mechanism, we …
