Residual Dynamic Mode Decomposition: Robust and verified Koopmanism
Matthew J. Colbrook, Lorna J. Ayton, Máté Szőke
Dynamic Mode Decomposition (DMD) describes complex dynamic processes through a hierarchy of simpler coherent features. DMD is regularly used to understand the fundamental character…
A calculus for flows in periodic domains
Peter J. Baddoo, Lorna J. Ayton
We present a constructive procedure for the calculation of 2-D potential flows in periodic domains with multiple boundaries per period window. The solution requires two steps: (i)…
Exact solutions for ground effect
Peter J. Baddoo, Melike Kurt, Lorna J. Ayton +1
"Ground effect" refers to the enhanced performance enjoyed by fliers or swimmers operating close to the ground. We derive a number of exact solutions for this phenomenon, thereby e…
Acoustic scattering by cascades with complex boundary conditions: compliance, porosity and impedance
Peter J. Baddoo, Lorna J. Ayton
We present a solution for the scattered field caused by an incident wave interacting with an infinite cascade of blades with complex boundary conditions. This extends previous stud…
Rapid noise prediction models for serrated leading and trailing edges
Benshuai Lyu, Lorna J. Ayton
Leading- and trailing-edge serrations have been widely used to reduce the leading- and trailing-edge noise in applications such as contra-rotating fans and large wind turbines. Rec…
An Analytic Solution for the Noise Generated by Gust-Aerofoil Interaction for Plates with Serrated Leading Edges
Lorna J Ayton, Jae Wook Kim
This paper presents an analytic solution for the sound generated by an unsteady gust interacting with a semi-infinite flat plate with a serrated leading edge in a background steady…
Aerodynamic noise from rigid trailing edges with finite porous extensions
A. V. Kisil, L. J. Ayton
This paper investigates the effects of finite flat porous extensions to semi-infinite impermeable flat plates in an attempt to control trailing-edge noise through bio-inspired adap…
