Journal ArticleDOI
Coherent structures in unsteady swirling jet flow
TL;DR: In this article, an LDA technique and phase-averaging analysis were used to study unsteady precessing flow in a model vortex burner, and the effect of coupling of secondary vortices was suggested as a mechanism of enhanced stability reflected in their increased axial extent.
Journal ArticleDOI
On the identification of helical instabilities in a reacting swirling flow
TL;DR: In this article, an experimental study of unsteady reacting flow in a lean premixed swirl-stabilized combustor has been performed using a high speed camera, LDV, chemiluminescence and acoustic probes.
Journal ArticleDOI
Experimental characterization of rotating flow field in a model vortex burner
TL;DR: In this paper, acoustic techniques, high speed filming and LDA were employed to characterize swirling jet flow in a model vortex burner, and phase-averaged analysis of the LDA data was used to reveal an instantaneous flow field spatial distribution and to determine the precessing vortex characteristics.
