Abstract
Low-temperature techniques were applied to the study of a hydrodynamic instability. High-precision results for the Nusselt number as a function of the Rayleigh number for liquid and gaseous helium revealed no singularities in , except at the convective threshold . For , a new turbulent state was found and characterized by measuring the frequency spectrum and the amplitude of .
