Maximizing the dynamic permeability during occlusions
- 48 Downloads
We study the dynamic permeability of a viscoelastic fluid flowing in an occluded tube due to either central or peripheral obstructions. We find that for occluded systems, the dynamic permeability decreases. We also find that the value of the dynamic permeability for the occluded systems, can be made as large as the dynamic permeability for the non-occluded system when the proper frequency is imposed to the flow.
