Curvature-based energy spectra revealing flow regime changes in Rayleigh-Bénard convection
Michael Mommert, Philipp Bahavar, Robin Barta +3
We use the local curvature derived from velocity vector fields or particle tracks as a surrogate for structure size to compute curvature-based energy spectra. An application to hom…

Condensation-induced flow structure modifications in turbulent channel flow investigated in direct numerical simulations
Philipp Bahavar, Claus Wagner
The turbulent flow of a fluid carrying trace amounts of a condensable species through a differentially cooled vertical channel geometry is simulated using single-phase direct numer…
