    Abstract:
    The paper describes in detail an apparatus for heat-transport measurements in shallow horizontal layers of fluid at low temperatures. High-precision results of convective heat transports as a function of the Rayleigh number R are presented for cylindrical cells of aspect ratio L equals 2. 08, 4. 72 and 57. The paper concentrates on the long-time behavior of Boussinesq systems. The measurements show that the convective onset near the critical Rayleigh number R//c is sharp within the experimental resolution of about 0. 1% of the Nusselt number N, even in laterally finite containers. Values of R//c, and of the initial slopes of N(R), are obtained and compared with predictions for different flow patterns. Refs.
