Effective Rheology of Bingham Fluids in a Rough Channel
We derive the volumetric flow rate versus pressure drop of a Bingham <br/>fluid in one-dimensional channels of variable apertures in the lubrication <br/>approximation. A characteristic length scale, $a^*$ characterizing the flow<br/>is introduced in order to distinguish between a...
