The application of an unsteady viscous flow around a bluff body has covered a wide range
of scientific fields. This paper reviews the wakes of different cross-sectional bluff bodies …

An effort is made to demonstrate the usefulness of critical-point concepts in the
understanding of flow patterns. Critical points are the salient features of a flow pattern; given …

Considerable confusion surrounds the longstanding question of what constitutes a vortex,
especially in a turbulent flow. This question, frequently misunderstood as academic, has …

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 …

Hot-wire anemometry (HWA) is one of the basic measuring techniques used by research
scientists and engineers working in fluid mechanics. It is applicable to a wide variety of flows …

This is a personal statement on the present state of understanding of coherent structures, in
particular their spatial details and dynamical significance. The characteristic measures of …

Ensemble-averaged statistics at constant phase of the turbulent near-wake flow (Reynolds
number≈ 21400 around a square cylinder have been obtained from two-component laser …

This paper overviews the dynamics of bluff body stabilized flames and describes the
phenomenology of the blowoff process. The first section of the paper provides an overview …

The structure of round jets in cross-flow was studied using flow visualization techniques and
flying-hot-wire measurements. The study was restricted to jet to freestream velocity ratios …

It is now well-known that the wake transition regime for a circular cylinder involves two
modes of small-scale three-dimensional instability (modes A and B), depending on the …
