Hi
I'm a PhD student of mechanical enginerring.
My thesis is about simulation and optimizing the natural gas double acting reciprocating engine.
this utility can produce electricity from recovering the potential energy of high pressure natural gas in CGS.
It works unlike the reciprocating compressor.
I am very confused about it and I don't know how to optimize it?
the most my problem is about the second law thermodynamic analysis (exergy destruction,...) , modeling the friction power (because there is oil free and I don't know the relatonship for it), modeling the inlet and outlet flow from slide valve and validating my data.
is there any body help me.
I reed more than 500 papers and books and thesis, but I can find only the basis information.
Thank you
