Test of a cooling loop with static head using JP8DryAir

Information

TestSimpleLoopWithStaticHeadJP8DryAir is a Modelica test model for a simple cooling loop using JP8DryAir, a mixture of JP8 jet fuel and dry air, as the working fluid.

This model extends TestSimpleLoopJP8DryAir by adding static head components to simulate pressure changes due to acceleration. The acceleration profile is sinusoidal along the x axis with a period of 60s and an amplitude of 9 m/s².
