Radiator model

[veeshy]

Is it possible to model a radiator with some effectiveness that radiates heat into the environment at some temperature?

Hi @veeshy,

There is no component for explicitly this right now, but I guess it should be possible. In fact, a student once implemented a night sky radiator model for her thesis (I am not allowed to share here). So what are your governing equations?

Oh cool! At this point, very simple like from https://www.engineeringtoolbox.com/radiation-heat-transfer-d_431.html:

times the emissivity of the radiator.

Then you can just start with a simple model:

Source, Simple heat exchanger, Sink and add a UserDefinedEquation (see the docs) with just that equation integrated. The surface temperature of the radiator would be calculated from the inlet and the outlet temperature of the SimpleHeatExchanger, the other parameters (area, emissivity, ...) are given to the equation as params. Maybe try to implement that and post your solution in case you cannot find something working.

I migrated this to discussions @veeshy. Did you succeed?
