Convective heat transport in slender cells is close to that in wider cells at high Rayleigh and Prandtl numbers
Ambrish Pandey, Katepalli R. Sreenivasan
Direct numerical simulations of turbulent convection at high Rayleigh numbers in large aspect ratio cells are challenging because of the prohibitive computational resources require…
Non-Boussinesq convection at low Prandtl numbers relevant to the Sun
Ambrish Pandey, Jörg Schumacher, Katepalli R. Sreenivasan
Convection in the Sun occurs at Rayleigh numbers, , as high as , molecular Prandtl numbers, , as low as , under conditions that are far from satisfying th…
A tenuous, collisional atmosphere on Callisto
Shane Carberry Mogan, Orenthal Tucker, Robert Johnson +7
A simulation tool which utilizes parallel processing is developed to describe molecular kinetics in 2D, single-and multi-component atmospheres on Callisto. This expands on our prev…
Laws of turbulence decay from direct numerical simulations
John Panickacheril John, Diego A Donzis, Katepalli R Sreenivasan
Inspection of available data on the decay exponent for the kinetic energy of homogeneous and isotropic turbulence (HIT) shows that it varies by as much as 100\%. Measurements and s…
Dynamics of three-dimensional turbulence from Navier-Stokes equations
K. R. Sreenivasan, V. Yakhot
We accomplish two major tasks. First, we show that the turbulent motion at large scales obeys Gaussian statistics in the interval 0 < Rlambda < 8.8, where Rlambda is the microscale…
Analyzing supergranular power spectra using helioseismic normal-mode coupling
Chris S. Hanson, Shravan Hanasoge, Katepalli R. Sreenivasan
Normal-mode coupling is a technique applied to probe the solar interior using surface observations of oscillations. The technique, which is straightforward to implement, makes more…
