Wave reflections and resonance in a Mach 0.9 turbulent jet
Robin Prinja, Eduardo Martini, Peter Jordan +2
This work aims to provide a more complete understanding of the resonance mechanisms that occur in turbulent jets at high subsonic Mach number, as shown by Towne et al. (J. Fluid Me…
Modeling closed-loop control of installation noise using Ginzburg-Landau equation
Ugur Karban, Eduardo Martini, Peter Jordan
Installation noise is a dominant source associated with aircraft jet engines. Recent studies show that linear wavepacket models can be employed for prediction of installation noise…
Modal decomposition of nonlinear interactions in wall turbulence
Ugur Karban, Eduardo Martini, André V. G. Cavalieri +1
Coherent structures are found in many different turbulent flows and are known to drive self-sustaining processes in wall turbulence. Identifying the triadic interactions which gene…
The effect of a flight stream on subsonic turbulent jets
Igor A. Maia, Guillaume Brès, Lutz Lesshafft +1
This study concerns a turbulent jet at Mach number , subject to a uniform external flow stream at . We assess the mechanisms that underpin the reduction in fluct…
Solutions to aliasing in time-resolved flow data
Ugur Karban, Eduardo Martini, Peter Jordan +2
Avoiding aliasing in time-resolved flow data obtained through high fidelity simulations while keeping the computational and storage costs at acceptable levels is often a challenge.…
Resolvent-based tools for optimal estimation and control via the Wiener-Hopf formalism
Eduardo Martini, Junoh Jung, André V. G. Cavalieri +2
The application of control tools to complex flows frequently requires approximations, such as reduced-order models and/or simplified forcing assumptions, where these may be conside…
Wave cancellation in jets with laminar and turbulent boundary layers: the effect of nonlinearity
Igor A. Maia, Peter Jordan, André V. G. Cavalieri
This paper presents a study on wave cancellation in forced jets. Building on recent work on real-time control of forced turbulent jets [1,2], we here assess the effect of jet upstr…
