The impact and spreading of droplets of complex fluids over surfaces occur in a variety of industrial applications. We will study the spreading of viscoplastic droplets under surface tension and gravity. The droplet converges to a final equilibrium shape once the driving stresses inside the droplet fall below the yield stress. Scaling laws are presented for the final radius and complemented with an asymptotic analysis for shallow droplets. Moreover, numerical simulations using the volume-of-fluid method and a regularized constitutive law and experiments with an aqueous solution of Carbopol are presented. In the end, we briefly present the other applications of droplets of yield stress fluids.
