Isentropic efficiency vs polytropic efficiency of a gas turbine

  1. Feb 10, 2014 #1
    My classmates and I are working on a senior design project where we optimize a baseline turbofan for supersonic cruise. We are a little confused about when to use polytropic vs isentropic efficiencies. I have read to begin with isentropic, however is there anyone who could explain a little more as to why?
