Propulsion • Thermodynamic Cycles of Gas Turbines • Brayton Cycle & Component Efficiencies
In an ideal Brayton cycle, heat addition in the combustor and heat rejection in the exhaust take place at:
(A) Constant pressure (isobaric)
(B) Constant volume (isochoric)
(C) Constant temperature (isothermal)
(D) Constant entropy (isentropic)
Answer Key:
A
Step-by-Step Verified Solution
### Solution: The Joule-Brayton cycle comprises two reversible isentropic processes (compression and expansion) and two reversible constant-pressure (isobaric) heat exchange processes. Correct: A.
