Slow flow of a Bingham fluid in a gap of slowly varying width

Show other versions (1)

The slow Poiseuille flow of a Bingham fluid in an infinitely long gap of slowly varying width is considered. A consistent analytical theory is developed using a lubrication scaling without deviating from the Bingham model. It is shown that for sufficiently small gap width variations there is a ri...
