Information
TestSimpleLoopJP8DryAir is a Modelica test model for JP8DryAir, a mixture of JP8, a jet propulsion fuel often used in military aircraft, and dry air.
It simulates a simple cooling loop using JP8 and dry air as refrigerant.
The loop includes a reservoir, centrifugal pump, a flow resistance, and a heating element. The 40 kW heating element adds thermal energy to the JP8 and dry air fluid and the pump maintained a temperature difference of 15°C across the conduction element by regulating the mass flow in the loop.
