In this dissertation, a modular-hierarchical framework for the pressure-driven, dynamic simulation and the rating of multi-stream heat exchangers is presented. A core component of the simulation framework are state-of-the-art design correlations for heat transfer and pressure drop, which ensure a realistic representation of the heat exchangers. The pressure-driven approach enables the robust simulation of forward, reverse, and zero flow scenarios, which is critical for an accurate prediction of heat exchanger dynamics. The simulation environment uses an innovative software infrastructure and can represent plate-fin, shell-and-tube and coil-wound heat exchangers, which are relevant for the modeling of process plants. The simulation environment includes different model depths for applications with different requirements.
