Abstract

The ambient temperature has the greatest effect on gas turbine performance, due to change of the turbine air inlet-temperature and pressure ratio. Thus, thermodynamic analyses exposed that thermal efficiency and specific output decrease with an increase of humidity and ambient temperature. The aim of this project is to design a heat exchanger for gas turbine inlet air cooling system in order to increase the efficiency of the gas turbine. The project attempts to maintain a constant temperature of the inlet of gas turbine engine irrespective ofthe increasing in ambient temperature. This has been accomplished by developing a mathematical model based on the step by step techniques so that variation of all design parameters can be calculated. The author has set the tube diameter and number of rows as the variables while the other geometry parameters remain constant throughout this project. At the end, a set of variables data is compared to predict the heat exchanger performance. The increasing of the tube diameter and number of rows has increased the heat transfer coefficient and pressure drop in the system. Among the samples, the optimum design of the heat exchanger consisted of 26 rows of horizontal tube and 0.06185 m tube inner diameter.
