Raising cycle efficiency by intercooling in air-cooled gas turbines

Future Aero Engine Designs: An Evolving Vision

“…Comparing the two concepts at their optimal OPR levels, for a given technology level, can make the intercooled core more attractive with respect to thermal efficiency and not just specific thrust. Canière et al (2006) and da Cunha Alves et al (2001) also reached the same conclusion about the thermal efficiency of the intercooled cycle while studying this concept for gas turbines used in power generation. Papadopoulos & Pilidis (2000) worked on the introduction of intercooling, by means of heat pipes, in an aero engine design for long haul applications.…”

Off‐Design Behavior Analysis and Operating Curve Design of Marine Intercooled Gas Turbine

“…Chen et al [13][14][15][16] studied a modeling approach for a triple-shaft open ICR gas turbine and obtained analytical formulas of the cycle's performance with 19 pressure drop losses, as well as optimizing the performance of the model cycle, reaching some valuable conclusions. Canière et al [17] studied the influence of various outlet pressure and temperature of intercooler and consequent various cooling air parameters on the gas turbine. Many of the aforementioned studies that carried out the effect of intercooler on gas turbine performance nevertheless did not value the effect of gas turbine performance back on intercooler enough.…”
