Abstract

The Nusselt number and the energy content of a convective fluid and its container have been measured for two structures formed at low Rayleigh numbers. The results for the energy content are discussed. It is found that this energy is accumulated mainly in the lateral walls of the container, these being parallel to the rolls formed.
