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 …

We analyse the long-time evolution of the three-dimensional flow in a closed cubic turbulent
Rayleigh–Bénard convection cell via a Koopman eigenfunction analysis. A data-driven …

We present an experimental study of flow structures in turbulent Rayleigh–Bénard
convection in annular cells of aspect ratios Γ= 1, 2 and 4, and radius ratio⋍ 0.5. The …

We study the topology and the temporal dynamics of turbulent Rayleigh–Bénard convection
in a liquid metal with a Prandtl number of 0.03 located inside a box with a square base area …

In this paper, we report on a direct numerical simulation (DNS) study of turbulent thermal
convection in mixed porous–pure fluid domains. The computational domain consists of a …

We investigate the statistics of dissipation rates in turbulent Rayleigh-Bénard convection
inside a cubic cell for air (P r= 0.7) in the Rayleigh number range 2× 10 6≤ R a≤ 10 9 using …

In this paper we present a numerical study of the dynamics of the Large-Scale Circulation
(LSC) in turbulent convection with a free surface. Our study is based on Large-Eddy …

The time-averaged strength $\langle\delta\rangle/\varDelta $ of a convective cellular pattern
and large-scale circulation (LSC) in the turbulence regime of turbulent Rayleigh–Bénard …

In this paper, we show that, in the presence of large-scale circulation (LSC), Taylor's
hypothesis can be invoked to deduce the energy spectrum in thermal convection using real …
