Performance evaluation of a gas turbine cycle with a pulse combustion system

This paper presents a comprehensive analysis of the effect of a pulse combustion system on the performance of a gas turbine cycle. The advantages of pulse combustors are numerous. The purpose of this paper, is to analyze theoretically this effect so that the resultant changes in performance can be estimated without experiment. In addition, this paper investigates the utilization of converting part of chemical energy of fuel into pressure energy in the combustion chamber of a gas turbine utilizing a pulse combustor. A computer code has been written to evaluate the cycle performance, thermodynamic characteristics of the cycle during operation as compared with a conventional cycle. The study describes the influence of the maximum possible pressure rise in combustion chamber, the heat addition ratio, maximum temperature and compressor pressure ratio on the performance parameters such as fuel consumption, net work output, excess air factor and thermal efficiency.
