Flowing Liquid Viscosity#

FlowingLiquid Viscosity = CONSTANT <float> [M/Lt]

Description / Usage#

This card is used to specify the model for the viscosity of liquid flowing through pores with the Brinkman model of flow through porous media, viz. see Media Type card with POROUS_BRINKMAN option. In the Brinkman model, the viscosity input through the Viscosity card is used as the Brinkman viscosity, and the viscosity input through this card is used in determining the hydraulic resistance. Detailed discussion of these two viscosities can be found by consulting the references below.

Definitions of the input parameters are as follows:


Name for the constant viscosity model.

  • <float> - The value of the viscosity.


Following is a sample card:

Flowing Liquid Viscosity = CONSTANT 101.0

This card is only applicable to the POROUS_BRINKMAN media type and results in a hydraulic resistance viscosity of 101.0.
