Abstract
An experiment is presented in which a buoyant vertical axisymmetric flow interacts with a 2D horizontal azimutal flow. It appears that the 2D flow becomes predominant upon the buoyant flow as soon as its velocities are of the order of one tenth of the velocity of the buoyant flow or larger. Finally, this turbulent flow is essentially characterised by a small number of large coherent structures which transport the heat as a passive scalar.
