Bispectral decomposition and energy transfer in a turbulent jet
Akhil Nekkanti, Ethan Pickering, Oliver T. Schmidt +1
We employ bispectral mode decomposition (BMD) to investigate coherent triadic interactions and nonlinear energy transfer in a subsonic turbulent jet. BMD extracts the flow structur…

Nonlinear dynamics of vortex pairing in transitional jets
Akhil Nekkanti, Tim Colonius, Oliver T. Schmidt
This study investigates the onset of linear instabilities and their later nonlinear interactions in the shear layer of an initially-laminar jet using a combination of stability ana…
