kEquilibrium

Kinetic energy equilibrium closure

Description

Provides algebraic equation for the equilibrium formulation of the kinetic energy for the continuous or dispersed phases. Therefore, it closes a scalar field.

Syntax

• phase: requires a string. If continuous it closes the continuous phase equation, otherwise if dispersed it closes the dispersed phase equation.

• otherPhaseK: requires a string. This model requires both the continuous and dispersed phase kinetic energy equations to be solved. Therefore, the user should enter the name of the kinetic energy field corresponding to the other phase.

NOTE: the user has to provide an equation for the otherPhaseK field! (see example below).
