Different between otto cycle brayton cycle

WebThe actual gas-turbine cycle is different from the ideal Brayton cycle since there are irreversibilities. Hence, in an actual gas-turbine cycle, the compressor consumes more … WebAs a final check, you can think of the Otto cycle's relationship to the Carnot cycle like the Rankine cycle's relationship to the Carnot cycle: Carnot is an idealized gold standard, and the Otto/Rankine versions represent an idealized real-life way of converting energy. So, the Carnot cycle is the theoretically "perfect" engine cycle.
