Abstract in different language:	The challenging issue that is addressed here is the modelling of turbulent phenomena, physically consistant, and reactive at the same time. The aim is, first, to understand these phenomena in order to elaborate a particle-based dynamic model, capable of accounting for a certain number of experimentally observed recognizable turbulent phenomena (consistency). Next, the aim is to achieve not only beautiful shapes, not only the fine dynamics slow and fleeting, of turbulent objects left to themselves, but the still richer movements that results from the interaction with man. (reactivity). This work presents a consistent connection with fundamental physics. However, it falls clearly in the field of computer graphics. We regard reactivity as a means to control a physically-based simulation of turbulent phenomena. We have elaborated several practicle-based dynamic models which produce the target phenomena. Thanks to particles, we have simulated the interaction (action and reaction) between several fluids as well as between fluids and solid objects (fixed or mobile, rigid or deformable). When moved by an operator, these objects enable him to wave a hand in the fluid, to guide it, or to manipulate a thurible. Eventually this coarse particle model is refined by a high-resolution dynamic model that adds the small-scale phenomena in the final animation.
