In three-dimensional hydrodynamic turbulence forced at large length scales, a constant
energy flux Π u flows from large scales to intermediate scales, and then to small scales. It is …

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 review we summarise the current status of the quasi-static magnetohydrodynamic
turbulence. The energy spectrum is steeper than Kolmogorov's k− 5/3 spectrum due to the …

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 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 …

Horizontally extended turbulent convection, termed mesoscale convection in natural
systems, remains a challenge to investigate in both experiments and simulations. This is …

Understanding the behavior of the kinetic energy spectrum and flux in two-dimensional (2D)
turbulent thermal convection remains a challenge. In this paper, using high-resolution direct …

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 …

We analyze the Prandtl number (Pr) dependence of spectra and fluxes of kinetic energy, as
well as the energy injection rates and dissipation rates, of turbulent thermal convection using …

Momentum-scalar coupling turbulence, a phenomenon observed in both natural and
engineering contexts, involves the intricate interaction between multicomponent scalars and …
