Fulcher dependence

Fulcher dependence

Ver: 2

DESCRIPTION

For a generalized Newtonian fluid, the constitutive equation has the form

S = 2 * eta * D

where S is the extra-stress tensor, D is the rate of deformation tensor, and eta is the viscosity.

The temperature dependence of the viscosity is denoted by a function H(T), where T is the temperature.
H(T) comes as a factor in the viscosity law:

eta(g,T) = F(g)*H(T)

For the Fulcher law, the function H(T) is written as follows :

H(T) = 10 ** ( -F1 + F2 / (T - F3) )

By default, F1 = F2 = F3 = 0 OPTIONS
