Numerical Analysis for the Prediction on the Effect of Heat Transfer Characteristics of Combined Cycle Gas Turbine Using Inter Cooler

Abstract: The gas turbine cycle has various uses in the present scenario. The gas turbines are mainly used for power generation in power plants. The gas turbine cycle is based on Brayton cycle. In the present work the parametric study of a gas turbine cycle model power plant with use of intercooler is proposed. The thermal efficiency, specific fuel consumption and net power output are simulating with respect to the temperature limits and compressor pressure ratio for a typical set of operating conditions. Simple gas turbine cycle calculations with realistic parameters are made and it confirms that increasing the turbine inlet temperature no longer means an increase in cycle efficiency, but increases the work done. The analytical study is done to investigate the performance improvement of gas turbine by the use of intercooler. The analytical formula for specific work and thermal efficiency are derived and analysed. The simulation results shows that decreasing the ambient temperature and increasing the pressure ratio can improve the performance of the intercooled gas turbine cycle further. The increase in ambient temperature cause decrease thermal efficiency, but the increase in turbine inlet temperature increases the thermal efficiency.
