Title Micro-scale flow on naturally occurring and engineered functional surfaces
Abstract Gravity-driven continuous thin liquid film flow and droplet motion over complex naturally occurring and engineered functional surfaces is modelled using lubrication theory. The associated time dependent, nonlinear coupled set of equations, for the film thickness/drop-height and pressure, are solved using a purpose written portable, objectorientated, parallel, time-adaptive full approximation storage (FAS) multigrid algorithm in order to maximise computational efficiency when fine-scale resolution is needed to obtain accurate, mesh independent solutions at the micro-scale. The robustness of the approach is demonstrated through the solution of three problems of practical interest: (i) the coating of pesticides on the surface of a leaf; (ii) free-surface planarisation during the manufacturing stage of a thermoelectric micro-device; (iii) the influence of gross inter-connected surface topography on droplet migration.
