Abstract

A model is presented which allows dynamic simulation of processes involving compression, expansion, heat generation and mass transfer in fluids. Equations are developed for various equipment models, based on one-dimensional flow approximation. Proposed solution methods for DAE systems are compared, on the basis of accuracy and computer usage. The architecture of a simulation package based on the object paradigm is described. This program has been validated with experimental data: surge onset in compression systems was predicted satisfactorily.
