Abstract: In this master thesis Modelica models for shell and tube heat exchangers was developed. The modelling focused on two configurations specifically; the TEMA E shell and tube heat exchanger with single-phase flow on the shell side and the TEMA G shell and tube heat exchanger with condensation on the shell side. The finite volume method (FVM), based on the models in the Modelon Base Library and the Heat Exchanger Library, was used. Correlations for the heat transfer coefficient and pressure drop were based on two different version of the Delaware method, the Chisholm two-phase multiplier and the method developed by Honda. Full coverage of the equations for all of the methods are given in the report. The models were tested in simulations and the qualitative analysis based on these simulations showed several effects that agreed with the theoretical predictions.
