Thin films of viscoplastic fluid Balmforth, Neil


Given suitable constitutive laws, thin-film equations can be derived for non-Newtonian fluids. In this talk, I will review the procedure for fluids with a yield stress, and then confront the resulting theory with experiments and computations that avoid the thin-layer approximation. The comparison with the computations illustrates that the theory can be effective, but the comparison with experiments highlights how additional physical considerations are often needed in realistic settings.
