A simulation model is derived which describes the thermo-fluid dynamics of cryogenic plate-fin heat exchangers. The geometry is resolved in three dimensions. Hence, the influence of the flow pattern and of the varying thermal inertia of individual components of the apparatus can be studied. Therefore, transient and steady-state simulation results are discussed. Because the model is fully automated, it can be used as part of an optimization framework. The automated design of a heat exchanger is shown as an examplary use case.
