Unformatted text preview: the turbine exit, ( , we apply the turbine efficiency: ) ( ) The turbine work becomes ( ) ( ) Thus, the Back Work Ratio (BWR) is defined as Regenerator Analysis: To find , we apply the regenerator effectiveness: ( ) ( ) To find the heat transferred from the turbine exhaust gas to the compressor exit gas, apply the steady-flow conservation of energy to the compressor gas side of the regenerator. ̇ ̇ ̇ ̇ ̇ ̇ ̇ ̇ = ( ) ( ) Using , we can determine the turbine exhaust gas temperature at the regenerator exit ̇ ̇ ̇ ̇ ̇ ̇ ̇ ( ̇ ) Heat supplied to cycle: Apply the steady-flow conservation of energy to the heat exchanger for process 5-3, we obtain a result similar to that for the simple Brayton cycle. ( ) ( Cycle thermal efficiency: The net work done by the cycle is ( The cycle efficiency becomes ) )...
