Abstract

Copyright © 2017 ASME. The problem of pneumatic volumes constituting a gas turbine engine gas path and their effect on an engine transient belongs to the topical problems of modern turbomachinery engineering. Many researchers have been trying to find the most resource efficient method of volume modeling. The associated urgent problem is the integration of the volume models with an engine model. Following the world trends, the present paper deals with the pneumatic volume simulation that considers different dynamic factors described with the mass, energy, and momentum conservation laws. The developed dynamic volume models were examined and compared. The comparison cases included temperature and pressure change at the volume entrance and pressure change at the volume discharge. To reduce the computation time, the linearization of model equations was also proposed and proved. Based on the comparison results, the guidelines and recommendations on the volume effect mathematical modeling and the volume model integration with the engine model have been made.
