Realistic sheared flow profile effects on acoustic impedance eduction in small 3D-ducts
Lucas A. Bonomo, Julio A. Cordioli, Edward J. Brambley +2
We investigate the influence of realistic sheared grazing flow on acoustic propagation in three-dimensional rectangular ducts. We show that conclusions reached in the literature ab…

Effects of the sheared flow velocity profile on impedance eduction in a 2D duct
Lucas A Bonomo, Edward J Brambley, Julio A Cordioli
Impedance eduction methods are the current standard approach to measure the impedance of acoustic liner under sheared grazing flow. The dedicated facilities for these methods consi…

Optimized Runge-Kutta (LDDRK) timestepping schemes for non-constant-amplitude oscillations
Aldaïr Petronilia, Edward James Brambley
Finite differences and Runge-Kutta time stepping schemes used in Computational AeroAcoustics simulations are often optimized for low dispersion and dissipation (e.g. DRP or LDDRK s…
