Hydrodynamic Stability of Periodically Unsteady Axisymmetric and Swirling Jets
Axisymmetric and swirling jets are generic flows that characterize many natural and man-made flows. These include cylindrical shear layer/mixing layer flows, aircraft jets and wakes, shedding of leading edge and wing tip vortices, tornadoes, astrophysical plasma flows and flows in mechanical …

Dynamics of swirling jets and flames
Even the simplest swirling jet flows possess an astonishing degree of complexity. This complexity is a two-edged sword, presenting both a unique opportunity to advance the science of fluid mechanics as well as a major barrier for a variety of engineering applications. In particular, swirling jet …

Swirling jets for the mitigation of hot spots and thermal Sstratification in the VHTR lower plenum
… state-of-the-art turbulence models and advanced swirling jet technology to mitigate the two issues. The primary research goals were to increase the heat transfer and mixing capacity of swirling jets, extend swirling jet theory, and to apply those advancements for the mitigation of the …

Enhancement of wastewater and sludge treatment processes by hydrodynamic cavitation
… investigate on the effectiveness of a modified swirling-jet device called Ecowirl reactor, patented by Econovation GmbH, Germany and produced and commercialized by Officine Parisi s.r.l., Italy. Experimental studies were carried out in order to evaluate the effects of different operative …

Point Doppler velocimetry measurements in circular jets
… measurements for 1 inch diameter standard, swirling, and annular jets have been made at a nominal exit velocity of 60 m/s, corresponding to a Reynolds number of 100,000. Measurements of radial profiles of mean and RMS velocities were taken for each jet from the jet exit to X/D=12 at nine …

Heat Transfer and Flow Measurements in an Atmospheric Lean Pre-Mixed Combustor
… of the flow fluctuation kinetic energy along the swirling jet shear layers. The capability of infrared (IR) thermography to image surface temperatures through a fused silica (quartz) glass was demonstrated at non-reacting conditions. IR thermography was then used to measure the non-reacting steady …

Impact of fuel and oxidizer composition on premixed flame stabilization in turbulent swirling flows : dynamics and scaling
… interaction between the flame and the turbulent swirling flow. Experimental data were used to construct the stability maps for different CH4-H2 mixtures and analyze the dynamic flame macrostructures and their transitions. A comparison with acoustically uncoupled combustion shows that the onset of …
