Air enters the compressor of a regenerative gas-turbine engine at 310K and 100kPa, where it is compressed to 900kPa and 650K. The regenerator has an effectiveness of 70 percent, and the air enters the turbine at 1400K. For a turbine isentropic efficiency of 90%, determine a) Determine the amount of heat transfer in the regenerator [15] b) Develop an expression for the thermal efficiency of the system [4] c) Using your expression developed determine the efficiency of the [6] system Figure 2: Regenerative Gas Turbine
