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…

Sessile condensate droplets as quasi-static wall deformations in direct numerical simulations of channel flow with condensation
Philipp Bahavar, Claus Wagner
Condensation is an important aspect of many flow applications due to the universal presence of humidity in the air at ambient conditions. For direct numerical simulations of such f…

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…
