Generic Modeling of Turbomachinery Components and Systems

Abstract

A turbomachinery system such as a power generation gas turbine engine, a thrust generation aero- engine, rocket propulsion, or a small turbocharger, consist of several sub-systems that we call components ([1,2,3,4]). Each component is an autonomous entity with a defined function within the system. Inlet nozzles, exit diffusers, combustion chambers, compressors, and turbines are a few component examples. A component may consist of several sub-components. A turbine or a compressor stage exhibits such a sub-component. The numerical models of components are called modules
