Detailed Description

This boundary condition provides a coupled temperature condition between multiple mesh regions. The regions are generally referred to as the:

- primary region, and

• baffle region

The primary region creates the baffle region and evolves its energy equation either:

• 1-D, normal to each patch face
• 2-D, normal and tangential components

The thermodynamic properties of the baffle material are specified via dictionary entries on the master patch

Patch usage
