Suppressing wall modes in confined rotating turbulent convection
Lázaro MartÃnez-OrtÃz, Maarten Minartz, Youri H. Lemm +3
In confined turbulent rotating convection, the largest vertical velocities are found near the sidewalls in the form of wave-like structures known as wall modes. These structures pe…

The Persistent Clock of Turbulent Thermal Convection
Lázaro MartÃnez-OrtÃz, Youri H. Lemm, Herman J. H. Clercx +1
The large-scale circulation (LSC) of turbulent convection is a prominent feature of its dynamics and forms the basis for descriptive theories. We show, using experimental and numer…

Scale-by-scale kinetic energy flux calculations in simulations of rotating convection
Youri H. Lemm, Xander M. de Wit, Rudie P. J. Kunnen
Turbulence is an out-of-equilibrium flow state that is characterised by nonzero net fluxes of kinetic energy between different scales of the flow. These fluxes play a crucial role…
