Abstract

In this study, a model to simulate the dynamic operation of regenerative gas turbines is described and the transient behaviour of a small engine equipped with a stationary recuperator is presented. The mathematical model of each component consisted of unsteady one-dimensional governing equations and steady state component characteristics. The equation set derived was solved by using a fully implicit numerical method. A realistic control unit model for speed control was likewise introduced to simulate the operation of real engines. Special emphasis was given to the thermal inertia of the recuperator metal that governs the dynamic characteristics of the engine. The dynamic characteristics were examined for a couple of load change modes such as stepwise and periodic load variations. Characteristic transient responses were then investigated and the dependence of transient response on the frequency of load variation was demonstrated.
