Membrane tortuosity
Tortuosity is widely used as a critical parameter to predict transport properties of porous media, such as rocks and soils. But unlike other standard microstructural properties, the concept of tortuosity is vague with multiple definitions and various evaluation methods introduced in different contexts. Hydraulic, electrical, diffusional, and thermal tortuosities are defined to describe differen… WebUsing the tortuosity,1 where is the dynamic viscosity of the fluid and k is a proportionality constant known as permeability .1 .Toa large extent, the proper …
