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…
Beyond optimal disturbances: a statistical framework for transient growth
Peter Frame, Aaron Towne
The theory of transient growth describes how linear mechanisms can cause temporary amplification of disturbances even when the linearized system is asymptotically stable as defined…
An empirical model of noise sources in subsonic jets
Ugur Karban, Benjamin Bugeat, Aaron Towne +3
Modelling the noise emitted by turbulent jets is made difficult by their acoustic inefficiency: only a tiny fraction of the near-field turbulent kinetic energy is propagated to the…
A Database for Reduced-Complexity Modeling of Fluid Flows
Aaron Towne, Scott T. M. Dawson, Guillaume A. Brès +8
We present a publicly accessible database designed to aid in the conception, training, demonstration, evaluation, and comparison of reduced-complexity models for fluid mechanics. A…
Space-time POD and the Hankel matrix
Peter Frame, Aaron Towne
Time-delay embedding is an increasingly popular starting point for data-driven reduced-order modeling efforts. In particular, the singular value decomposition (SVD) of a block Hank…
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.…
