3rd test example: IndirectCooling

A prescribed heat sources dissipates its heat through a thermal conductor to the inner coolant cycle. It is necessary to define the pressure level of the inner coolant cycle. The inner coolant cycle is coupled to the outer coolant flow through a thermal conductor.
Inner coolant's temperature rise near the source is the same as temperature drop near the cooler.
Results:
output explanation formula actual steady-state value
dTSource Source over Ambient dtouterCoolant + dtCooler + dTinnerCoolant + dtToPipe 40 K
dTtoPipe Source over inner Coolant Losses / ThermalConductor.G 10 K
dTinnerColant inner Coolant's temperature increase Losses * cp * innerMassFlow 10 K
dTCooler Cooler's temperature rise between inner and outer pipes Losses * (innerGc + outerGc) 10 K
dTouterColant outer Coolant's temperature increase Losses * cp * outerMassFlow 10 K
