This thesis studies the instability of a viscoplastic film flowing down an inclined plane. The viscoplastic fluids need to exceed a minimal stress τ_y to flow. Understanding this problem makes it possible to better explain the physical mechanisms involved in the destructive power of roll-waves in mud and lava flows. Unlike for Newtonian fluids, this has not yet been accurately measured for viscoplastic flows. We cannot then compare the existing theoretical models. So, we have designed a model experimental setup. The experimental setup is a channel with a variable slope angle, in which a permanent flow of a Herschel-Bulkley fluid is established. Controlled frequency and amplitude pertubations are imposed at the entrance of the channel to gen...
