****************** Power Law Exponent ****************** :: Power Law Exponent = CONSTANT [] ----------------------- **Description / Usage** ----------------------- This card is used to specify the model for the power-law exponent parameter of the **POWER_LAW, CARREAU, BINGHAM, CARREAU_WLF, CURE,** **SUSPENSION, FILLED_EPOXY, POWERLAW_SUSPENSION, CARREAU_SUSPENSION,** and **HERSCHEL_BULKLEY** fluid options of the *Liquid Constitutive Equation* card. Definitions of the input parameters are as follows: +-----------------+---------------------------------------------------------------------------------------------------------+ |**CONSTANT** |Name of the model for the power-law exponent. | | | | | | * - the value of the power-law exponent. This variable is normally *n* in the constitutive laws.| +-----------------+---------------------------------------------------------------------------------------------------------+ |**LEVEL_SET** |Name of the model for level-set dependent power law exponent. Specifically used for changing the exponent| | |from one constant value on the negative side of the interface to another constant value on the positive | | |side. The model requires three floats: | | | | | | * - the value of power-law exponent in the negative regions of the level set function. | | | * - the value of power-law exponent in the positive regioons of the level-set function. | | | * 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. | +-----------------+---------------------------------------------------------------------------------------------------------+ ------------ **Examples** ------------ The following is a sample card that sets the power law exponent to 0.2: :: Power Law Exponent = CONSTANT 0.2 ------------------------- **Technical Discussion** ------------------------- See Description/Usage for *Liquid Constitutive Equation* card. -------------- **References** -------------- No References.
