For an ideal Brayton cycle with ideal regeneration, the thermodynamic conditions are : T max =T3 =1500 K, T min=T 1=300 K. Please find the γ P,IB(CASA),IRG MAX and the thermodynamic efficiency at this γ P. Theoretically, what is the maximum thermodynamic efficiency for this Brayton cycle with ideal regeneration? What is the γ P for this maximum thermodynamic efficiency and can you achieve this maximum efficiency in actual applications? Why?
