Mathematical Model and Simulation of a Plate Heat Exchanger Operating as Steam Generator

This paper shows a one-dimensional mathematical model for a plate heat exchanger operating as steam generator; the generator is one of the main components of an absorption heat transformer. The model shows the global heat and mass balances, the heat and mass balances in the interface, the model of heat transfer, the heat transfer coefficients and the friction factor for the generation process. This is a complete model for the heat and mass transfer to determine the concentration and temperature profiles. Commercial software Agilent HP Vee Pro 7.5 was used for the simulation.
