Description

The Controlled Heat Flow Rate Source block represents an ideal source of thermal energy that is powerful enough to maintain specified heat flow at its outlet regardless of the temperature difference across the source.

Connections A and B are thermal conserving ports corresponding to the source inlet and outlet, respectively. Port S is a physical signal port, through which the control signal that drives the source is applied. You can use the entire variety of Simulink^® signal sources to generate the desired heat flow variation profile. The heat flow through the source is directly proportional to the signal at the control port S.

The block positive direction is from port A to port B. This means that positive signal at port S generates heat flow in the direction from A to B.

Examples

Heat Conduction Through Iron Rod

How thermal blocks can model a long iron rod that is fixed to a hot base at one end and exposed to air along its length and at its free end. The rod is an extended surface that undergoes conduction along its length and convection with air in the direction perpendicular to its length. Extended surfaces are often used as fins to cool a solid.
