VARIABLE TURBULENT SCHMIDT - Turbulent Schmidt number models

VARIABLE [TURBULENT] SCHMIDT [NUMBER] [MODEL] model \ [ITERATIONS iter] [zone_selector]

This keyword can be used to activate the variable turbulent Schmidt number capability. The available models currently only include constant zonal values.

Keyword Options

[MODEL] model

This keyword option selects the turbulent Schmidt number model to be used. The table below summarizes the available models.

	model		Model Type
	`FREESTREAM`		constant
	`CONSTANT {value}`		constant

The default setting is to use the constant FREESTREAM turbulent Schmidt number, as specified by the SCHMIDT keyword.

The CONSTANT model allows a different value to be specified for each zone.

ITERATIONS iter

The transport equations to be solved are organized into logical "groups" that are solved together. It also allows multiple iterations of a specific group (i.e., sub-iterations) for each "iteration per cycle". If NAVIER-STOKES ITERATIONS is defaulted, this corresponds to iter iterations of the turbulent Prandtl model equations for each iteration of the mean flow equations.

The default value for iter is one, indicating that each iteration per cycle corresponds to one iteration of the turbulent Prandtl model equations.
