Information

The model is designed to test the component Flow1Dfem (fluid side of a heat exchanger, finite element method).
This model represent the fluid side of a heat exchanger with an applied external heat flow. The operating fluid is liquid water.
During the simulation, the inlet specific enthalpy, heat flux and mass flow rate are changed:

• t=0 s, Step variation of the specific enthalpy of the fluid entering the heat exchanger. The outlet temperature should undergo a step change 10 s later.
• t=30 s, Step variation of the thermal flow entering the heat exchanger lateral surface. The outlet temperature should undergo a ramp change lasting 10 s
• t=50 s, Step variation of the mass flow rate entering the heat exchanger. Again, the outlet temperature should undergo a ramp change lasting 10s

Simulation Interval = [0...80] sec
Integration Algorithm = DASSL
Algorithm Tolerance = 1e-6
