Non-Boussinesq low-Prandtl number convection with a temperature-dependent thermal diffusivity
Ambrish Pandey, Jörg Schumacher, Katepalli R. Sreenivasan
In an attempt to understand the role of the strong radial dependence of thermal diffusivity on the properties of convection in sun-like stars, we mimic that effect in non-Oberbeck-…
Solar east-west flow correlations that persist for months at low latitudes are dominated by active region inflows
Chris S. Hanson, Thomas L. Duvall, Aaron C. Birch +2
Context: Giant-cell convection is believed to be an important component of solar dynamics. For example, it is expected to play a crucial role in maintaining the Sun's differential…
A general formulation for computing spherical helioseismic sensitivity kernels while incorporating systematical effects
Jishnu Bhattacharya, Shravan M. Hanasoge, Katepalli R. Sreenivasan
As helioseismology matures and turns into a precision science, modeling finite-frequency, geometric and systematical effects is becoming increasingly important. Here we introduce a…
Quantum Computation of Fluid Dynamics
Sachin S. Bharadwaj, Katepalli R. Sreenivasan
Studies of strongly nonlinear dynamical systems such as turbulent flows call for superior computational prowess. With the advent of quantum computing, a plethora of quantum algorit…
The area rule for circulation in three-dimensional turbulence
Kartik P. Iyer, Sachin S. Bharadwaj, Katepalli R. Sreenivasan
An important idea underlying a plausible dynamical theory of circulation in three-dimensional turbulence is the so-called Area Rule, according to which the probability density func…
Detection of exomoons in simulated light curves with a regularized convolutional neural network
Rasha Alshehhi, Kai Rodenbeck, Laurent Gizon +1
Many moons have been detected around planets in our Solar System, but none has been detected unambiguously around any of the confirmed extrasolar planets. We test the feasibility o…
Small-scale isotropy and ramp-cliff structures in scalar turbulence
Dhawal Buaria, Matthew P. Clay, Katepalli R. Sreenivasan +1
Passive scalars advected by three-dimensional Navier-Stokes turbulence exhibit a fundamental anomaly in odd-order moments because of the characteristic ramp-cliff structures, viola…
Dissipation range of the energy spectrum in high Reynolds number turbulence
Dhawal Buaria, Katepalli R. Sreenivasan
We seek to understand the kinetic energy spectrum in the dissipation range of fully developed turbulence. The data are obtained by direct numerical simulations (DNS) of forced Navi…
Oscillations Modulating Power Law Exponents in Isotropic Turbulence: Comparison of Experiments with Simulations
Kartik P. Iyer, Gregory P. Bewley, Luca Biferale +2
Inertial-range features of turbulence are investigated using data from experimental measurements of grid turbulence and direct numerical simulations of isotropic turbulence simulat…
Turbulence is an ineffective mixer when Schmidt numbers are large
Dhawal Buaria, Matthew P. Clay, Katepalli R. Sreenivasan +1
We solve the advection-diffusion equation for a stochastically stationary passive scalar , in conjunction with forced 3D Navier-Stokes equations, using direct numerical simulati…
Scaling exponents saturate in three-dimensional isotropic turbulence
Kartik P. Iyer, Katepalli R. Sreenivasan, P. K. Yeung
From a database of direct numerical simulations of homogeneous and isotropic turbulence, generated in periodic boxes of various sizes, we extract the spherically symmetric part of…
