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 …

Tarang is a general-purpose pseudospectral parallel code for simulating flows involving
fluids, magnetohydrodynamics, and Rayleigh–Bénard convection in turbulence and …

The study of instabilities in the convection of rotating fluids is one of the classical topics of
research. However, in spite of more than five decades of research, the instabilities and …

Rayleigh–Bénard convection with large-Prandtl number (P) is studied using a low-
dimensional model constructed with the energetic modes of pseudospectral direct numerical …

Transition to hyperchaotic regimes in Rayleigh-Bénard convection in a square periodicity
cell is studied by three-dimensional numerical simulations. By fixing the Prandtl number at …

Constructing simpler models, either stochastic or deterministic, for exploring the
phenomenon of flow reversals in fluid systems is in vogue across disciplines. Using direct …

We study the stability of steady convection rolls in two-dimensional Rayleigh–Bénard
convection with free-slip boundaries and horizontal periodicity over 12 orders of magnitude …

We present a detailed bifurcation structure and associated flow patterns for low–Prandtl-
number (P= 0.0002, 0.002, 0.005, 0.02) Rayleigh-Bénard convection near its onset. We use …

We investigate the dynamics of flow reversals close to the onset of Rayleigh-Bénard
convection (RBC) of electrically conducting low Prandtl number (Pr) Boussinesq fluids in the …
