(Why) Jets quantise trapped acoustic modes
Brandon Yeung, Michael N. Stavropoulos, Vincent Jaunet +2
High-subsonic turbulent jets trap acoustic modes in their potential core. The modes lie in narrow frequency bands that are -wide in Strouhal number, . By studying a Mac…
Mesh-Free Hydrodynamic Stability
Tianyi Chu, Oliver T. Schmidt
A specialized mesh-free radial basis function-based finite difference (RBF-FD) discretization is used to solve the large eigenvalue problems arising in hydrodynamic stability analy…
Large-scale streaks in a turbulent bluff body wake
Akhil Nekkanti, Sheel Nidhan, Oliver T. Schmidt +1
A turbulent circular disk wake database (Chongsiripinyo \& Sarkar, \textit{J. Fluid Mech.}, vol. 885, 2020) at Reynolds number is inte…
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…
Gappy spectral proper orthogonal decomposition
Akhil Nekkanti, Oliver T. Schmidt
Experimental spatio-temporal flow data often contain gaps or other types of undesired artifacts. To reconstruct flow data in the compromised or missing regions, a data completion m…
Spectral Proper Orthogonal Decomposition using Multitaper Estimates
Oliver T. Schmidt
The use of multitaper estimates for spectral proper orthogonal decomposition (SPOD) is explored. Multitaper and multitaper-Welch estimators that use discrete prolate spheroidal seq…
