Swirling flows are of considerable practical importance. They are used for example to
increase heat transfer in pipes or to stabilize flames at a distance from the injector unit by …

More than two decades ago the first strong experimental results appeared suggesting that
turbulent flows might not be asymptotically independent of their initial (or upstream) …

This paper presents an experimental investigation on swirling jets with well-defined initial
conditions. The axial, radial, and azimuthal velocity components, with their respective …

A finite-volume solver is used to compute the cyclonic motion in a vortex chamber assuming
steady, incompressible, and inviscid flow conditions. A parametric campaign enables us to …

It was hypothesized that counter-rotating swirling jets enhanced rotational momentum while
multiple swirling jets (MSJ) reduced velocity decay along spreading direction. This study …

The present experimental investigation is devoted to the mixing characteristics of a passive
scalar in the near-field region of a moderately swirling jet issuing from a fully developed …

TURBULENT jets have continued to interest researchers for many years, both because of
their numerous applications and their importance to our fundamental understanding of …

An experimental investigation of swirl and wake strength influence on axisymmetric turbulent
wake evolution was conducted. A novel wake generator design wire mounted in a wind …

IMPROVING the efficiency of turbulent jet mixing can produce several performance
enhancements for aircraft, including decreased jet noise, lower plume temperatures …

This work presents a semi-empirical correlation for the swirl number of a radial-type swirl
generator under different conditions of both the Reynolds number and the angle of the …
