# Does real gas's entropy increase in $T$-$S$ diagram of Brayton Cycle efficiency?

I got T-S diagram for efficiency of Brayton Cycle, which includes ideal cycle (black line), real cycle (red line) and GE's cycle (blue line), can't understand the entropy, whether it increases or decreases, I draw a diagram of it and as u can see the entropy of GE's cycle goes between ideal cycle and real cycle, is it right or no? Got presentation this week and sure that professor will ask more detailed explanation for this diagram. If someone knows please explain.

• What's GE's cycle mean? – Chet Miller Nov 27 '18 at 14:16
• GE Power - company's name which has the gas turbine with highest efficiency. – Jakha Rakhmatzoda Nov 28 '18 at 11:17
