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 …

In this paper, we report that reversals of the large-scale circulation in two-dimensional
Rayleigh–Bénard (RB) convection can be suppressed by imposing sinusoidally distributed …

To understand how internal flow structures manifest themselves in the global heat transfer,
we study the correlation between different flow modes and the instantaneous Nusselt …

In this paper we present scaling results of a FFT library, FFTK, and a pseudospectral code,
Tarang, on grid resolutions up to 819 2 3 grid using 65536 cores of Blue Gene/P and …

We present experimental studies of higher-order modes of the flow in turbulent thermal
convection in cells of aspect ratio (is ahead of the minimum of the amplitude of the LSC; and …

We derive a formula for the Péclet number (Pe) by estimating the relative strengths of
various terms of the momentum equation. Using direct numerical simulations in three …

The coexistence of multiple turbulent states was reported in several recent studies in
different flows. We present in this work that multiple turbulent states also exist for thermal …

We consider long-term data from direct numerical simulations of turbulent Rayleigh–Bénard
convection inside two-dimensional (2-D) square cells. For the range of Rayleigh numbers …
