Yield Stress#

Yield Stress = CONSTANT <float> [M/Lt2]

Description / Usage#

This card is used to specify the model for the yield stress parameter, \(τ_y\), of the BINGHAM and HERSCHEL_BULKLEY model options of the Liquid Constitutive Equation card. Definitions of the input parameters are as follows:

CONSTANT

Name of the model for the yield stress.

  • <float> - the value of the yield stress, τy, which has the dimensions of stress, in whatever units are consistent with the problem and marks the transition from solid-like to fluid-like behavior for the Bingham-Carreau-Yasuda model.

Examples#

The following is a sample card that sets the yield stress to 100:

Yield Stress = CONSTANT 100.
