Résumé

The attachment of fluid jets to walls when blown close to these walls is known by the name of the Coanda effect and is widely used in practice, e.g. for the ventilation and air conditioning of rooms. When a jet of air cooler than the ambient air is blown horizontally along the ceiling, the jet adheres to the ceiling over a given distance even though it is heavier than the ambient air. The aim of this paper is to provide a satisfactory explanation for the phenomenon.
