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 …

Large-eddy simulations of turbulent Rayleigh-Bénard convection were conducted for a fluid
of Prandtl number Pr= 0.7 confined in a cube, for Rayleigh numbers of 10 6 and 10 8. The …

We present a numerical study of the reversals and reorientations of the large-scale
circulation (LSC) of convective fluid in a cylindrical container of aspect ratio one. We take …

We investigate the origin of various convective patterns for Prandtl number P= 6.8 (for water
at room temperature) using bifurcation diagrams that are constructed using direct numerical …

We present a study of several systems in which a large-scale field is generated over a
turbulent background. These large-scale fields break a symmetry of the forcing by selecting …

We present the characteristics and dynamics of large-scale circulation (LSC) in turbulent
Rayleigh–Bénard convection (RBC) inside a cubic cell. The simulations are carried out for a …

The effect of viscoelasticity on the flow and heat transport in the Rayleigh–Bénard
convection (RBC), a frequently encountered phenomenon in nature and industry, in a …

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

We present a direct numerical simulation to investigate the dynamics and statistics of
reorientations of large-scale circulation (LSC) in turbulent rotating Rayleigh-Bénard …

We report the occurrence of flow reversals induced by the attractor-merging crisis in
Rayleigh-Bénard convection of electrically conducting low-Prandtl-number fluids in the …
