Adaptive spectral proper orthogonal decomposition of tonal flows
Brandon C. Y. Yeung, Oliver T. Schmidt
An adaptive algorithm for spectral proper orthogonal decomposition (SPOD) of mixed broadband-tonal turbulent flows is developed. Sharp peak resolution at tonal frequencies is achie…
RBF-FD discretization of the Navier-Stokes equations on scattered but staggered nodes
Tianyi Chu, Oliver T. Schmidt
A semi-implicit fractional-step method that uses a staggered node layout and radial basis function-finite differences (RBF-FD) to solve the incompressible Navier-Stokes equations i…
Finite rotating and translating vortex sheets
Bartosz Protas, Stefan G. Llewellyn Smith, Takashi Sakajo
We consider the rotating and translating equilibria of open finite vortex sheets with endpoints in two-dimensional potential flows. New results are obtained concerning the stabilit…
A stochastic SPOD-Galerkin model for broadband turbulent flows
Tianyi Chu, Oliver T. Schmidt
The use of spectral proper orthogonal decomposition (SPOD) to construct low-order models for broadband turbulent flows is explored. The choice of SPOD modes as basis vectors is mot…
Resonance and propulsion performance of a heaving flexible wing
S. Michelin, S. G. Llewellyn Smith
The influence of the bending rigidity of a flexible heaving wing on its propulsive performance in a two-dimensional imposed parallel flow is investigated in the inviscid limit. Pot…
