mobility tensor

mobility tensor

[mō′bil·əd·ē ‚ten·sər]
(plasma physics)
A second-rank tensor whose product with the electric field vector for a plane wave in a plasma gives a vector equal to the average velocity of electrons or ions; components of both vectors are in phasor notation.

where [LAMBDA] is a fourth order tensor, called the mobility tensor which is essentially the inverse of the relaxation time of the polymer fluids, c is the conformation tensor, [rho] is the fluid density, Q is anisotropic viscosity matrix that is related to viscous dissipation, L is coupling parameter between the velocity gradient field and the structural tensor field, and A is Helmholtz free energy function represented by a combination of invariants of the conformation tensor, which can be written as follows based on the Hookean model:
The general expression for the mobility tensor presented by Beris and Edwards is as follows [19]:
They concluded that the mobility tensor type has a pronounced effect on the predicted results [22].
