Turbulent flows are characterized by the non-linear cascades of energy and other inviscid
invariants across a huge range of scales, from where they are injected to where they are …

The progress in our understanding of several aspects of turbulent Rayleigh-Bénard
convection is reviewed. The focus is on the question of how the Nusselt number and the …

The properties of the structure functions and other small-scale quantities in turbulent
Rayleigh-Bénard convection are reviewed, from an experimental, theoretical, and numerical …

We present a numerical scheme geared for high performance computation of wall-bounded
turbulent flows. The number of all-to-all communications is decreased to only six instances …

Hydrodynamic flows exhibit turbulent behaviour which is not well understood till date. When
a fluid is in a gravitational field, the flow becomes even more complex due to the gravity …

In this paper, we describe the recent developments in thefield of buoyancy-driven turbulence
with a focus on energy spectrum andflux. Scaling and numerical arguments show that the …

The ultimate regime of thermal convection, the so-called Kraichnan regime [RH Kraichnan,
Phys. Fluids 5, 1374 (1962)], hitherto has been elusive. Here numerical evidence for that …

Using high-resolution direct numerical simulation and arguments based on the kinetic
energy flux Π u, we demonstrate that, for stably stratified flows, the kinetic energy spectrum E …

The Ra and Pr number scaling of the Nusselt number Nu, the Reynolds number Re, the
temperature fluctuations, and the kinetic and thermal dissipation rates is studied for …
