Heat sources can be used to simulate heat generation from a volume. For instance, it is useful when dealing with electronic equipment and HVAC systems, to model heat generated by chips on a circuit board, or by car engines in a garage.
SimScale currently supports heat sources within two analysis types:
In both cases, the heat source has to be assigned to a volume which can be one of the following:
In the simulation tree, navigate to “Advanced Concepts” and add a Heat Source. Two types of heat sources are supported:
This type of source has to be used when the total power emitted by the heating element is known. The user is required to provide this value and to choose the relevant region of the domain.
This type of source has to be used when the power density is known. This is simply total power per unit volume. This quantity is often provided for batteries and fuel cells, for example.
If single heat sources are applied to multiple entities, each of them produces the prescribed power value. For example, a heat source with a value of 100W is assigned to two entities, each will emit 100W.
When assigning a heat source, one can either select the solid in the viewer (switching to the volume selection mode), or use the check box on the top-right corner of the screen.
