Relative accuracy of turbulence simulations using pseudo-spectral and finite difference solvers

Akash Rodhiya, Shashwat Bhattacharya, Mahendra K Verma

For a single timestep, a spectral solver is known to be more accurate than its finite-difference counterpart. However, as we show in this paper, turbulence simulations using the tw…

Scale-resolved turbulent Prandtl number for Rayleigh-Bénard convection at $Pr = 1 0^{- 3}$

Shashwat Bhattacharya, Dmitry Krasnov, Ambrish Pandey +2

We present a framework to calculate the scale-resolved turbulent Prandtl number $P r_{t}$ for the well-mixed and highly inertial bulk of a turbulent Rayleigh-Bénard mesoscale convecti…
