********************* **Advective Scaling** ********************* :: Advective Scaling = {model_name} ----------------------- **Description / Usage** ----------------------- This material property card permits the user to scale only the advective terms in one or more of the species transport equations by a fixed constant. This may be useful when solving problems with non-standard concentrations or for stability reasons. A single {model_name} is available; it and its parameters are described below: +-----------------------+-------------------------------------------------------------------------------------+ |**CONSTANT** |Model used to specify the advective scaling. | | | | | | * - the index of the species equation to which the advective scaling will | | | occur. | | | * - scaling, the actual value for the multiplicative scaling factor. | +-----------------------+-------------------------------------------------------------------------------------+ ------------ **Examples** ------------ Here is an example of the card: :: Advective Scaling = CONSTANT 0 0.0 In this case, the card is being used to eliminate the advective terms in the conservation equation for species 0. ------------------------- **Technical Discussion** ------------------------- The advective terms in the species conservation equations take the form, u ⋅ ∇c where c is the species concentration and u the fluid velocity. -------------- **References** -------------- No References.
