In this PhD thesis, we show that the physics of dissipative effects, that is completely governed by the local Reynolds number, has non trivial consequences on velocity increment statistics. Thanks to simple dimensional arguments, we propose a unified picture, in the framework of the multifractal formalism, of the "acceleration" of the propagator observed in ...
