The equation of motion given by Chase and Willis (1992), for deforming
porous matrix can be written as following:
(7-51)
where T 5 is the shear stress tensor for the solid matrix.
The jump mass balance equations, given by Slattery (1972) can be
simplified to express the boundary conditions as:
(7-52)
(7-53)
(7-54)
The superscript a denotes a quantity associated with the dividing surface,
which is moving at a macroscopic velocity of w°, and n a is the unit
vector normal to the dividing surface. r°, rf and r? are the rates of
addition of mass of the porous matrix, the th phase, and the species i
