This paper describes a general computational method for predicting the dynamic behavior of gas turbines and their components during transient processes of the most varied kinds. Starting from the conservation laws of fluid and thermodynamics, formulas are derived with which non-stationary processes in the most important components of the gas turbine can be accurately predicted. As an example, the transient behavior of an open-cycle gas turbine with extreme changes in load is calculated. The comparison between the calculations and measurements demonstrates the accuracy and the reliability of the computational method. Although this method has so far been applied only to a broad range of power-generating gas turbines extending from open-cycle turbines to air storage turbines, it is also suitable for the simulation of aircraft gas turbines.
