Mixing of a Plain Jet into a Swirling Crossflow
Many gas turbine combustion systems employ swirl to help mix fuel and air and subsequently stabilize the reaction. In the case of liquid fuels, strategic introduction of the liquid into the swirling flow can provide improved combustion performance. In the present work, radial injection of a plain jet into a swirling flow is considered. A large body of work is available in the literature for liq...
متن کاملCavitation bubble behavior inside a liquid jet
The growth and collapse of laser-induced vapor cavities inside axisymmetric free-falling liquid water jets have been studied. Bubbles of different size are generated at various distances from the jet axis and the effects on the jet interface are recorded by means of ultrafast cinematography. The configuration is characterized by two dimensionless parameters: the bubble to jet diameter ratio and...
متن کاملDispersion of Evaporating Droplets in a Swirling Axisymmetric Jet
The effects of swirl and vaporization on droplet dispersion are investigated in the near region of a two-phase, swirling, heated jet. Simulations are based on the numerical solution of time-dependent, axisymmetric gas-phase equations.Droplets’ trajectories are tracked byusingaLagrangianapproach.Forall of the swirl cases investigated, the droplet dispersion exhibits a nonmonotonic behavior, with...
متن کاملComputational Study of Jet Cavitation Inception Using a Phase Analysis
Cavitation inception in the near-field of high Reynolds number axisymmetric jets is analyzed using a simplified computational model. The model combines an axisymmetric vorticitystreamfunction finite-difference scheme for the simulation of the unsteady flow field. Using a simplified representation, microscopic bubbles are injected at the jet inlet. The motion of these bubbles is tracked in a Lag...
متن کاملLes of a Free Annular Swirling Jet - Dependence of Coherent Structures on a Pilot Jet and the Level of Swirl
The paper presents large eddy simulation of unconfined swirling jets. In the first part, an unconfined annular jet is investigated for swirl numbers ranging from 0 to 1.2. The impact of the swirl on the mean flow and the precessing vortex structures in this flow is analysed. In the second part of the paper, a co-annular pilot jet is introduced near the axis. The investigations show that the add...
