Regeneration can only increase the efficiency of a Brayton cycle when working fluid leaving the turbine is hotter than the working fluid leaving the compressorQuestion 5Select one:a.TRUEb.FALSE
Solution
b. FALSE
Explanation: Regeneration in a Brayton cycle is used to improve the efficiency of the cycle by reducing the amount of heat input required. This is achieved by transferring heat from the exhaust gas (working fluid leaving the turbine) to the compressed air (working fluid leaving the compressor) before it enters the combustion chamber. This process is beneficial regardless of whether the working fluid leaving the turbine is hotter or cooler than the working fluid leaving the compressor. The key factor is that the exhaust gas is typically still hotter
