KriegerDoughertyViscosity

Syntax

Defined in transportProperties dictionary.

viscosityModel temperatureDependentViscosity;

nu              scalar;
tempFieldName   "T";
tempFunction    Function1;

  • nu = default (kinematic) viscosity

  • tempFieldName = the temperature field name (default: T)

  • tempFunction = the (kinematic) viscosity as function of temperature. This is a freely configurable Function1 object.

Examples

viscosityModel temperatureDependentViscosity;

nu              1e-6;
tempFieldName   "T";
tempFunction    table
(
    (300  1e-6)
    (310  9e-7)
    (320  7e-7)
);

Description

Caluclates the viscosity as a function of the field specified by tempFieldName. The function itself is a Function1 object, typically it will be specified in a tabulated manner using the table setting.

Restrictions

None.
