1 PERFORMANCE ANALYSIS OF GAS TURBINE CYCLE AT VARIABLE SPECIFIC HEAT

Abstract

The most important thermodynamic property used in heat release calculations is the specific heat ratio. The functions proposed in the literature for the specific heat ratio is temperature dependent. The various models of temperature dependant specific heat ratio is discussed in the literature and with a study of these functions it is a very clear to consider specific heat is a linear function in terms of temperature to a certain limits of temperature. The thermodynamic performance of gas turbine cycle with temperature dependant variable specific heats of working fluid is studied and temperature dependent specific heat ratio functions were derived. The specific heats are a function of temperature and thus make a difference. As the specific heats of a working fluid is always a function of temperature, it is necessary to consider this aspect in the practical gas turbine cycles. The thermodynamic performance of Gas turbine cycle with variable specific heats of working fluid with tempera...
