Abstract

The functional dependences of hydraulic permeability and electrokinetic properties on the composition and material properties of charged hydrated tissues (e.g., articular cartilage) during a one dimensional steady permeation experiment have been derived using the recently developed triphasic theory [Lai et al., 1991]. The results showed that these properties vary within the tissue due to physical interactions between the flowing fluid (including the flowing ions) and the charged porous-permeable solid matrix. Fundamental relationships governing these effects depend on the tissue water content, fixed charge density, solid matrix elastic moduli (i.e., strain-dependent permeability) and the frictional coefficients between the porous-permeable solid matrix and the interstitial fluid. In addition, a new method for the determination of the fixed charge density within the tissue is proposed.
