Abstract

Low Prandtl number thermal convection is being studied, owing to the interest in geophysical applications and in many technical problems. Earth’s liquid-core convection (at Pr ~ 0.1) and sodium heat exchangers are only two examples among many. As pointed out by Thual (1992), however, large attention is devoted to this problem also because its study contributes to a large amount of theoretical progress in nonlinear dynamics and turbulence. In addition, many numerical and experimental works are available in literature for Prandtl numbers in the range 0.7–7, while less is known when this parameter assumes lower values; this is the main motivation for the present study.
