Investigation into Computer Simulation of the Dynamic Response of a Gas TurbineEngine

摘要

Transient performance of gas turbines has a strong bearing on output andcomponent life. For this reason, several articles have been written on the dynamic simulation of gas turbine systems in electrical generation, cogeneration, and marine applications. These models provide a basis for this present work. This paper describes a mathematical and computer model that was developed to investigate the dynamic response of a simple (no reheat, regeneration, or other auxiliary equipment) single-shaft gas turbine system. The model uses design parameters normally incorporated in gas turbine design (e.g. load coefficient, flow coefficient, and deHaller Number) as well as compressor and turbine stage geometry and compressor and turbine material properties. Also incorporated is a combustion chamber model. Other input parameters are included to enable the model to be adaptable to various system sizes and environments.
