Conditions for optimum isentropic efficiency

  1. Feb 9, 2017 #1
    1. The problem statement, all variables and given/known data
    Ive looked through several published journals online trying to find an experiment that I can use as background research for my report, something I can compare my findings to but im just wasting lots of time that I could be doing the rest of my report so what im trying to find out is how mass flow rate and rotational speed of an axial flow compressor affect the isentropic efficiency.
    My results showed that the optimum efficiency was at the highest rotational speed and mass flow rate so im guessing that high rotational speed and mass flow rate conditions are required for optimum isentropic efficiency but I need some clarification, Thanks.

    (1) What do you understand the term isentropic efficiency to mean ? How is it defined for a compressor ?

    (2) The compressor that you are working on is a commercially produced one .

    If you search you might be able to find the published performance specification . This type of specification usually includes one or more charts showing pressure/flow rate/torque/efficiency and other information .
