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…
Dynamics of small bubbles in turbulence in non-dilute conditions
Xander M. de Wit, Hessel J. Adelerhof, André Freitas +3
Turbulent flows laden with small bubbles are ubiquitous in many natural and industrial environments. From the point of view of numerical modeling, to be able to handle a very large…
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…
Experiments on rapidly rotating convection: the role of the Prandtl number
Hannah M. Clercx, Rudie P. J. Kunnen
Flows at planetary scales are generally driven by buoyancy and influenced by rotation. Rotating Rayleigh-Bénard convection (RRBC) is a practical and simple model that can be used…
Tracking the rotation of light magnetic particles in turbulence
Chunlai Wu, Rudie P. J. Kunnen, Ziqi Wang +3
Particle-laden turbulence involves complex interactions between the dispersed and continuous phases. Given that particles can exhibit a wide range of properties, such as varying de…
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…
