Abstract

In this paper we present some results of an extensive campaign of direct numerical simulations of Rayleigh–Bénard convection at high Prandtl numbers (10⁰ ≤ Pr ≤ 10⁴) and moderate Rayleigh numbers (10⁵ ≤ Ra ≤ 10⁹). In particular, we examine the Nusselt and the Reynolds number dependences on Ra and Pr. A short discussion on the characteristic flow velocity is also presented.
