Equation Closures

Description

Closures for user-defined equations introduced via the auxiliary equations utility. They are specified for each auxiliary equation.

Syntax

In eulerianFilteredTFM, each equation has one closure that is composed of several sub-closures. Such sub-closures are declared in the equation sub-dictionary using:

• subClosures: requires a list of strings. List of sub closures used to close the auxiliary equation.

In addition, sub-closures are defined in dedicated sub-dictionaries.

Examples

In the equation sub-dictionary:

 subClosures  kEquilibrium;

 kEquilibrium
 {
   phase         dispersed;
   otherPhasek   k.air;
 }

This example provides the equilibrium closure to the equilibrium closure for the granular temperature.

Available sub-closures

scalar field	vector field	tensor field
kinetic energy equilibrium
phase volume fraction variance equilibrium
