When considering Gas Turbine efficiency study, should we focus on Isentropic efficiency or Polytropic efficiency??
We should consider the isentropic efficiency, since it is more easy to calculate the actual temperature at each components.
Noted Jayanti. Tq
isentropic efficiency varies with pressure ratio of turbine. so, if you want to study the effect of the pressure ration, it would be better to use polytropic efficiency.
Noted Mohammad. Tq
We have to consider the Poly tropic Efficiency because of ease in algebra.
