Pressure driven lubrication flow of a Bingham fluid in a channel: A novel approach

•We investigate the flow of a Bingham fluid in a channel of non uniform width.•We model the unyielded part of the fluid using a global integral approach.•We determine an integro-differential for the pressure and solve it numerically.•We find constraints on the channel profile that predict the breaki...
