Gas Turbine Thermodynamic Process

The first step toward designing a new gas turbine is to generate its thermodynamic cycle diagram. This diagram provides the essential information about the connection between the turbine inlet temperature TIT, the compressor pressure ratio \( \pi_{c} \) and the gas turbine thermal efficiency \( \eta_{th} \). Starting with a simple GT-cycles, in the following sections methods are introduced to determine the GT-efficiency and its improvement by changing the gas turbine configurations and cycles.
