Aerodynamic noise from rigid trailing edges with finite porous extensions
Kisil, Anastasia; Ayton, Lorna Jane (Cambridge University PressJournal of Fluid Mechanics, 2018-02-10)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 adaptations. Specifically the problem of sound ...

An Iterative Wiener--Hopf method for triangular matrix functions with exponential factors
Kisil, AnastasiaThis paper introduces a new method for constructing approximate solutions to a class of Wiener{Hopf equations. This is particularly useful since exact solutions of this class of Wiener{Hopf equations, at the moment, cannot ...

Stability analysis of matrix Wiener–Hopf factorization of Daniele–Khrapkov class and reliable approximate factorization
Kisil, Anastasia (Royal Society PublishingProceedings of the Royal Society of London A, 2015-05-06)This paper presents new stability results for matrix Wiener–Hopf factorization. The first part of the paper examines conditions for stability of Wiener–Hopf factorization in the Daniele–Khrapkov class. The second part of ...

The relationship between a strip Wiener--Hopf problem and a line Riemann--Hilbert problem
Kisil, Anastasia (OUPIMA Journal of Applied Mathematics, 2015-03-31)In this paper, the Wiener–Hopf factorization problem is presented in a unified framework with the Riemann–Hilbert factorization. This allows to establish the exact relationship between the two types of factorization. In ...
