Summary of the scope of application for thermodynamic models sought
Thread Content
In numerical simulations, the choice of thermodynamic model is very important. The use of equation of state methods has now become a trend in the development of thermodynamics; these methods can be employed to calculate polar systems, high-pressure systems, and other special types of systems. However, there are no clear guidelines regarding the temperature and pressure ranges for which these thermodynamic models are applicable, and the information available in thermodynamics textbooks is not always comprehensive or up-to-date. I hope that those who are engaged in research in this field or have experience in it can summarize these aspects, so that future calculations can be carried out more conveniently. I invite experts to help address this issue, and discussions from everyone are welcome
Watch the thermodynamics tutorials for Pro11 and Aspen; they explain things in great detail, especially the Aspen tutorials. Once you’ve seen them, you’ll understand a lot. In fact, although thermodynamic methods (referred to as property methods in Aspen) are important, choosing the right one is merely a minor prerequisite for conducting accurate simulation calculations.
