Objectives
1) To conduct a theoretical study to look into the interplay between various driving mechanisms on the microscale of a SLIPS, and hence the interaction between the working fluid and the lubricating fluid, when the working fluid is under an applied pressure gradient or shear force on the macroscale; 2) To investigate, through mathematical modeling or numerical simulation, effective or macroscopic slip arising from flow of a viscous fluid over a SLIPS as a function of the microtexture, properties of fluids, deformation of the fluid interface, and hydrodynamics of the bulk flow; 3) To investigate drag reduction for pressure-driven flow through channels of various geometries with SLIPS walls; 4) To investigate the self-healing capability and the draining loss of lubricant as a function of the microtexture, properties of the fluids, and hydrodynamics of the bulk flow.
