Contact Interface

The contact interface type is used to join together either of the following to permit conjugate heat transfer between the regions:

Two solid regions, either from the same continuum or from different continua

A fluid and solid region

Application

Conjugate heat transfer between solid regions

Modeling

A thermal contact resistance per unit area,

, for conjugate heat transfer may be specified. The relation between the heat flux across the contact interface,

, and the temperature difference,

, is given by:

(2)

Compatibility

The contact interface cannot be used between regions belonging to fluid continua
