Relaminarization of turbulent pipe flow induced by streamwise traveling wave wall transpiration and its scaling
Christian Bauer, Claus Wagner
In technical applications, more than 90\% of the energy required to pump the fluids through pipes is dissipated by turbulence near the wall. In this respect, streamwise traveling w…

The Lagrangian kinetic energy cascade in Rayleigh-Bénard convection
Robin Barta, Claus Wagner, Ron Shnapp
Rayleigh-Bénard convection at high Rayleigh number exhibits turbulence superimposed on large-scale circulation. While buoyancy forces drive the flow at certain scales, how kinetic…

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…
