A mathematical model is constructed to study the evolution of a vertically oriented thin liquid film draining under gravity when there is an insoluble surfactant with finite surface viscosity on its free surface. Lubrication theory for this free film results in three coupled nonlinear partial differ
The speed at which an annular liquid collar drains under gravity g in a vertical tube of radius a, when the tube has an otherwise thin viscous liquid lining on its interior, is determined by a balance between the collar's weight and viscous shear stresses confined to narrow regions in the neighborho
## Abstract This paper describes the development of an annular chamber designed for preparative freeβflow electrophoresis which can operate at voltages up to 20Β kV, electric fields up to 65Β kV/m, and power densities as high as 10Β MW/m^3^. This apparatus uses counterβrotating fluid vortices to stabi
