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…
