CYU 10-9.1 Select the correct statement regarding the Brayton cycle with regeneration.
(a) The greater the effectiveness of the regenerator, the greater the thermal efficiency of the Brayton cycle.
(b) The thermal efficiency of the Brayton cycle increases as a result of regeneration.
(c) The use of a regenerator is only recommended when the turbine exhaust temperature is higher than the compressor exit temperature.
(d) All of the above
CYU 10-9.2 Select the correct statement regarding the Brayton cycle with regeneration.
(a) In an ideal regenerator, the air leaving the compressor is heated to the turbine exit temperature.
(b) Regeneration is less effective at lower pressure ratios.
(c) The thermal efficiency of an ideal Brayton cycle with regeneration depends only on the ratio of the minimum to maximum temperatures and the specific heat ratio.
(d) None of the above
