The concentration fluctuation c of diluted fluorescein dye, a high-Schmidt-number passive scalar (Sc=ν/D ≈ 2000, ν and D are the fluid momentum and dye diffusivities, respectively), is measured in the wake of a circular cylinder using a single-po

The stirring and mixing properties of one-phase coaxial jets, with large outer (annular) to inner velocity ratio ru = u2/u1 are investigated. Mixing is contemplated according to its geometrical, statistical and spectral facets with particular attenti

The Laser Induced Fluorescence (LIF) technique was used to determine a few characteristics of a high Schmidt number (Sc) passive scalar (fluorescein) in the near-wake of a circular cylinder. The mean and rms concentration indicate that increasing the

An investigation of the near-field flow structure of coaxial jets with large outer to inner velocity ratio ru has been conducted. Since in all cases ru>1, the outer jet dominates the near-field flow structure. Two flow regimes are identified dependin

We report on a new flow pattern transition observed in a coaxial jet configuration. Above a critical momentum ratio between the outer and the inner stream, it is found experimentally that the inner potential core breaks down into an unsteady recircul

This study focuses on the effects of the geometry of the coaxial injectors on the near-field flow structure. The dependence of the flow structure on the annular gap e = (D 2 - D 1 )/2 is considered. The effect of the exit velocity profile is discusse

Laser-induced fluorescence (LIF) diagnostics and highspeed, real-time digital image acquisition techniques are combined to map the composition field in a water mixing layer. A fluorescent dye, which is premixed with the lowspeed freestream fluid and

Quantitative measurements of the instantaneous concentration field of a high Schmidt number passive scalar (fluorescein : Sc = v/D ≈ 2000, v and D are respectively the fluid viscosity and the scalar diffusivity) in the near-wake of a cylinder are m
