Effects of controlled vortex generation and interactions in transverse jets

Abstract: This experimental study examined the effects of controlled vortex generation and interactions created by axisymmetric excitation of a transverse jet, with a focus on the structural and mixing characteristics of the flow. The excitation consisted of a novel double-pulse forcing waveform applied to the jet, where two distinct temporal square wave pulses were prescribed during a single forcing period. The two distinct pulses produced vortex rings of different strength and celerity, the strategic selection of whic… Show more

“…Applications to combustion systems include the injection of cooling air into hot combustion products or the premixing of fuel and oxidizer. Many investigations have been devoted to the optimization and control of mixing induced by transverse jets, including the work of Moussa et al [24], Bowman [25], Vermeulen et al [26], Margason [27], Holdeman [28], Smith and Mungal [29], Johari et al [30], M'Closkey et al [31], Shan and Dimotakis [32], Ekkad et al [33], Sau and Mahesh [34], Karagozian [35], Gevorkyan et al [36], Harris et al [37], among others.…”
