Plate Attributes: Face Convection Coefficient

Description

Assigns a convection coefficient to surfaces of selected plate elements.

Applicable only to heat transfer analysis.

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

Different convection coefficients can be defined on the -z and +z surfaces.

The coefficient can be scaled as a function of time and/or temperature.

Convection coefficient attributes are load case dependent.

Value

Convection coefficient at the plate surface.

Factor vs Time table

A table that scales the coefficient as a function of time.

Applicable only to the transient heat solver.

Factor vs Temperature table

A table that scales the coefficient as a function of temperature.

Applicable only to nonlinear heat transfer analysis.

Surface

The surface on which the attribute is applied.

• +z

  Convection is on the +z surface of the plate.

• -z

  Convection is on the -z surface of the plate.

• Both

  Convection is on both surfaces of the plate.
