Brayton vs carnot cycle
WebNov 1, 2024 · The improducible power due to shape of the Carnot vs. Brayton cycle is given in Fig. 22; which is a measure of the ideal Brayton cycle in comparison to the 100% Carnot cycle scale. Fig. 22 shows that at higher altitudes less power is lost, therefore, the Brayton cycle approaches the Carnot cycle power output. WebThe work of heat engine in one cycle is equal to the area, bounded by the curve 1-2-3-4. Sector 2-3 shows the advantage of the thermodynamic Humphrey cycle, compared with the Brayton cycle.
