Vortex motion is one of the basic states of a flowing continuum. Intere-ingly, in many cases
vorticity is space-localized, generating concentrated vortices. Vortex filaments having …

Vortex breakdown of nominally axisymmetric, swirling incompressible flows with jet-and
wake-like axial velocity distributions issuing into a semi-infinite domain is studied by means …

The nature of the vortex end (or the “tail end” or “tip”) in reverse-flow centrifugal gas cleaning
equipment, cyclones and swirl tubes, has been studied by visualization using a stroboscope …

This chapter reviews striking features of boundary-layer instabilities induced by different
mechanisms and related to transition to turbulence in rotating flows with walls. Besides its …

The flow produced in an enclosed cylinder of height-to-radius ratio of two by the counter-
rotation of the top and bottom disks is numerically investigated. When the Reynolds number …

An efficient and accurate numerical scheme is proposed to solve the incompressible Navier–
Stokes equations in a bounded cylinder. The scheme is based on a projection method …

Time-dependent swirling flows inside an enclosed cylindrical rotor–stator cavity with aspect
ratio H/R= 4, larger than the ones usually considered in the literature, are studied. Within a …

An efficient and accurate numerical scheme is presented for the three-dimensional Navier–
Stokes equations in primitive variables in a cylinder. The scheme is based on a spectral …

The complex turbulent swirling flow inside cyclone separators was studied using high-fidelity
large eddy simulations (LESs). Using the appropriate subgrid-scale LES model, flow …

Unsteady 3-D numerical simulations and 3-D LDA measurements of an annular jet with a
blockage ratio of 0.89 and Reynolds number 4400 are presented. At these flow conditions …
