The heat exchanger enthalpy source is a device which introduces or removes a specified amount of heat flow in a region. The distribution of this set amount of heat source or sink through the space of the region is established by local temperature with respect to a user-specified reference temperature. In this way, the distribution of heat within the fluid is similar to what would be seen with a heat exchanger. It is associated with one fluid stream only and is a net source or sink with the model instead of a transfer from one continuum to another.
This device is a very simple way to incorporate a known heat load into (or from) a model with a minimum of effort and a minimal computational burden. Sample applications include air conditioner evaporators, condensers, charge air coolers, radiators, electric heaters and electronic devices.
The method is relatively insensitive to mesh size and will utilize resolution corresponding the grid fineness.
The heat exchanger enthalpy source is activated by the Energy Source Option.
