Theoretical and Numerical Approaches for Calculating the Performances of an Industrial Turboshaft

Abstract

The paper presents two approaches for the thermodynamic cycle analysis applied to gas turbines. For a 1,500 kW industrial engine, still in development, different configurations are considered, the most complex including intercooling and heat recovery components. The theoretical algorithm, a conventional compromise between simplicity and accuracy, is presented in the first part of the paper. The second part describes a numerical approach for calculating the operating cycle of a gas turbine and presenting the methods for preparing the particular required format. The conclusions are related to the future work necessary for finalizing a numerical code able to analyse different gas cycle options allowing to obtain the desired output power and efficiency.
