Layer Heat Source
Use this subnode to add an internal heat source Qs within a thin layer. Add one or more heat sources. If this subnode is applied on a pair, note that the source term is applied on the source side.
Layer Heat Source
Select the General source (the default) or Heat rate button to define Qs.
•
For General source enter a value or expression for Qs as a heat source per volume.
•
For Heat rate define the heat rate Ps. In this case Qs = Ps ⁄ V where V = Ads with A equal to the area of the boundary selection.
You can specify the source to be a harmonic perturbation in a frequency domain analysis. To mark the source as being a harmonic perturbation, right-click the node and choose Harmonic Perturbation. Note that this updates the node’s icon. See Theory for Harmonic Heat Transfer for more details.
Thin Layer
Theory for Heat Transfer in Thin Structures
The Heat rate option is only available when the Layer type is Thermally thin approximation or Thermally thick approximation in the Thin Layer parent node.
With General layer type, a general source user input, Qs,i, is available for each layer. In this case the layers are numbered from the upside (Layer 1) to the downside.
