Özet

The flow characteristics of liquids modeled by the Bingham plastic constitutive relation through microtubes were numerically studied. The wall roughness effect in a microtube was characterized by using a roughness-viscosity model. The model was used to modify the laminar Bingham plastic flow equations in microtubes by introducing a location dependent apparent viscosity. The results show that the flow friction in microtubes is considerably larger than the predictions of the conventional theory based on uniform viscosity.
