This review article focuses on the near-field flow characteristics of coaxial circular jets that,
despite their common usage in combustion processes, are still not well understood. In …

The influence of the thickness of the boundary layer developing over the surface of an
axisymmetric bluff body upon its base pressure and near-wake flow is analyzed …

In this paper, planar time-resolved particle image velocimetry measurements are reported in
the near-field of a coaxial jet at velocity ratios, ru= 0.66, 1.0 and 1.32. At each ru, at least two …

An experimental study was conducted to better understand the mixing properties of coaxial
jets as several parameters were systematically varied, including the velocity ratio, density …

The near-field region of a coaxial jet having inner to outer diameter ratio di/do= 0.39 is
investigated experimentally for four ratios of annular to central jet velocities of η= 0.18, 0.48 …

Detailed laboratory experiments were performed to study the dynamics and mixing
properties of vertically discharged sand-water coaxial jets in stagnant water. The effects of …

Characteristics of co-flowing jets at subsonic and correctly expanded sonic Mach numbers
were investigated numerically for three different lip thicknesses namely, 0.2Dp, 1.0Dp and …

The control of co-flowing jets by varying lip thickness has been studied experimentally. Lip
thickness is defined as the thickness of primary nozzle wall separating primary jet and …

In this study, the characteristics of the flow in a rotating circular cylinder are investigated
experimentally and numerically. The hot-wire anemometry is used to measure the mean …

Direct numerical simulations are performed to analyze the flow dynamics and the mixing
properties of natural (unforced) and excited coaxial jets at moderate Reynolds number. First …
