Creating a Shell Region
Define a shell region on the surface of the airfoil.
The DMP model permits mass within its liquid phase to transfer to a liquid film. In Simcenter STAR-CCM+, liquid films exist only within a shell region. A shell region is a cell layer that is located on top of an existing boundary. Although the cell layer has zero-thickness in geometry, it contains a finite thickness relevant to the quantity being modeled. In the case of a liquid film, the thickness is the depth of the film layer.
In this tutorial, you define a shell region on the surface of the airfoil, so that the liquid film associated with the shell region can receive impinging droplets.
To create a shell region:
-
Right-click the
node and select
Create Shell Region.
A shell region, Foil shell, is created within the Regions node. Also, an interface between the shell region and Region 1 is created automatically within the Interfaces node.
- Save the simulation.
