Jet-edge interaction: linear and non-linear frequency-selection mechanisms
Michael N. Stavropoulos, André V. G. Cavalieri, Lutz Lesshafft +1
We consider a round turbulent jet grazing a rectangular plate angled at . Through sound pressure measurements, the tonal dynamics associated with jet-edge interaction are…

Onset of global instability in a premixed annular V-flame
Chuhan Wang, Christopher M. Douglas, Yu Guan +2
We investigate self-excited axisymmetric oscillations of a lean premixed methane--air V-flame in a laminar annular jet. The flame is anchored near the rim of the centrebody, formin…

Acoustic resolvent analysis of turbulent jets
B. Bugeat, U. Karban, A. Agarwal +2
We perform a resolvent analysis of a compressible turbulent jet, where the optimisation domain of the response modes is located in the acoustic field, excluding the hydrodynamic re…
