Abstract
This paper is concerned with the thermal instabilities occurring in a horizontal duct which is submitted to a mixed convection phenomenon. I f we consider that the physical signals have a deterministic aspect, t he system will be assumed as following a non-linear dissipative dynami c leading to a chaotic state. This state will be characterized and the transition to turbulence brought to the fore. More, we show how the p hysical mechanisms, responsible for these instabilities, induce differ ent evolution of the space phase trajectory in a cross-section. We res trict this study to a descriptive aspect of the thermal behaviour of t his system.
