In this paper, diphasic flows driven by pressure gradient in channels of a few hundred of micrometres square sections are studied. At this scale, the interfacial effects are dominating and the instabilities processes are generally studied from the experimental point of view. The instability is a well-known hydrodynamic instability due to surface tension namely the Plateau-Rayleigh instability. In this work, tridimensional numerical simulations are presented to understand this phenomenon and more generally to study the behaviour of diphasic fluids evolving in square microchannels.
