Thermal WLF Constant2#

Thermal WLF Constant2 = CONSTANT <float> [T]

Description / Usage#

This card is used to specify the thermal constant 2 of the CARREAU_WLF viscosity model in the Liquid Constitutive Equation card. Definitions of the input parameters are as follows:


Name of the model for Thermal Constant2.

  • <float> - the value of \(c_2\), in the equation representing the temperature-dependent shift factor for the CARREAU_WL constitutive model.


Name of the model for level-set dependent WLF thermal constant 2. Allows for this thermal constant 2 level to be a function of the level-set field. Specifically used for changing the thermal constant 2 from one constant value on the negative side of the interface to another constant value on the positive side. The model requires three floats:

  • <float1> - the value of thermal constant 2 in the negative regions of the level set function.

  • <float2> - the value of thermal constant 2 in the positive regioons of the level-set function.

  • <float3> Length scale over which the transition occurs. If this parameter is set to zero, it will default to one-half the Level-Set Length Scale value specified.


The following is a sample card that sets the Thermal WLF Constant2 to 0.1.

Thermal WLF Constant2 = CONSTANT 0.1
