33.4.13 Sutherland Law Dialog Box

The Sutherland Law dialog box allows you to set the coefficients for Sutherland's law for viscosity. This dialog box will open when you select sutherland in the drop-down list next to Viscosity in the Create/Edit Materials dialog box. See Section  8.4.2 for details about the items below.

Controls

Methods   contains options for selecting the Two Coefficient Method or the Three Coefficient Method.

C1, C2   set the coefficients $C_1$ and $C_2$ in Equation  8.4-5 in SI units. These inputs will appear if you select the Two Coefficient Method.

Reference Viscosity   sets the reference viscosity $\mu_0$ in Equation  8.4-6. This input will appear if you select the Three Coefficient Method.

Reference Temperature   sets the reference temperature $T_0$ in Equation  8.4-6. This input will appear if you select the Three Coefficient Method.

Effective Temperature   sets the effective temperature $S$ in Equation  8.4-6. This input will appear if you select the Three Coefficient Method.
