Direct numerical simulations (DNS) of turbulent Rayleigh-Bénard convection for a liquid metal with Pr = 0.025 are used to perform statistical analysis, in particular to evaluate the turbulent diffusion term in the temperature variance equation. These results are compered with DNS based predictions by a standard model of the turbulent diffusion term in the temperature variance equation and by a model which was recently developed by the authors.
