Scale-resolved turbulent Prandtl number for Rayleigh-Bénard convection at $\mathbf{Pr}=10^{-3}$

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…
