Face Attributes: Heat Transfer Convection Ambient Temperature

Description

Assigns a convection ambient temperature to selected faces.

When the geometry is automeshed, plates created on the face will inherit the convection ambient temperature attribute (see Plate Attributes: Face Convection Ambient Temperature).

Models uniform heat flow via convection through the surface to or from an ambient environment. The attribute is paired with a convection coefficient attribute, which together define the heat flow rate.

Different ambient temperatures can be defined on the -z and +z surfaces.

The ambient temperature can be scaled as a function of time.

Convection ambient temperature attributes are load case dependent.

Dialog

Value

Convection ambient temperature on the surface.

Temperature vs Time table

A table that varies the ambient temperature as a function of time.

Applicable only to the transient heat solver.

Surface

The surface on which the attribute is applied.

• +z

  Ambient temperature is on the +z surface.

• -z

  Ambient temperature is on the -z surface.

• Both

  Ambient temperature is on both surfaces.
