Transition to dilatation-dominated isothermal compressible turbulence
Shadab Alam, Christoph Federrath, Jörg Schumacher
The kinetic energy dissipation rate is of central importance for small-scale statistics in turbulent flows. Here, we report a transition to the dilatation-dominated regime of three…
Lagrangian single-particle, multi-particle and topological analyses in turbulent Rayleigh-Bénard convection
Matti Ettel, Roshan J. Samuel, Michael Chertkov +1
We present three-dimensional direct numerical simulations of turbulent Rayleigh-Bénard convection (RBC) in the Lagrangian frame of reference for Rayleigh numbers $10^5 \leq Ra \le…
Heat transport in magnetohydrodynamic duct flow regimes with conducting and insulating walls
Andreu Queralt McBride, Dmitry Krasnov, Yuri Kolesnikov +1
The flow of a liquid metal (LM) in a rectangular duct segment, subject to a uniform transverse magnetic field and uniform heating at the side walls is explored in an ample paramete…
Turbulent mesoscale convection in the Boussinesq limit and beyond
Shadab Alam, Dmitry Krasnov, Ambrish Pandey +4
Mesoscale convection covers an intermediate scale range between small-scale turbulence and the global organization of the convection flow. It is often characterized by an order of…
