Abstract

This paper presents the results of an on-going project to develop ThermoCycle; an open Modelica library for the simulation of low-capacity thermodynamic cycles and thermal systems. Special attention is paid to robustness and simulation speed since dynamic simulations are often limited by numerical constraints and failures; either during initialization or during integration. Furthermore; the use of complex equations of state (EOS) to compute thermodynamic properties significantly decreases the simulation speed. In this paper; the approach adopted in the library to overcome these challenges is presented and discussed.

Nyckelord
