33.4.16 Carreau Model Dialog Box

The Carreau Model dialog box allows you to set the parameters for the non-Newtonian Carreau model for viscosity. This dialog box will open when you select carreau in the drop-down list next to Viscosity in the Create/Edit Materials dialog box. See Section  8.4.5 for details about the items below.

Controls

Methods   allows you to select the type of dependency on the viscosity.

Shear Rate Dependent   is where the viscosity is dependent on the shear rate.

Shear Rate and Temperature Dependent   is where the viscosity is dependent on the shear rate and the temperature.

Time Constant, lambda   sets the time constant $\lambda$ in Equation  8.4-21.

Power-Law Index   sets the power-law index $n$ in Equation  8.4-21.

Zero Shear Viscosity, Infinite Shear Viscosity   set the zero and infinite shear viscosity limits $\eta_0$ and $\eta_\infty$ in Equation  8.4-21.

Reference Temperature, T_alpha   sets the reference temperature $T_0$ in Equation  8.4-21.

Activation Energy/R, alpha   is the ratio of the activation energy to the thermodynamic constant $\alpha$ in Equation  8.4-19.
