USING THE EXERGY METHOD TO ASSESS THE EFFICIENCY OF GAS TURBINE SUPERCHARGING SYSTEMS OF PISTON ENGINES

The features of the application of the exergy method for determining the loss of gas operability in gas turbine supercharging systems, depending on the boost level of piston engines, are considered. Exergy balances for various of gas turbine supercharging systems of piston engines are presented. It is shown that exergetic efficiency of pulse and isobaric turbocharging system with an average effective pressure 1.71 MPa equal to, respectively, 0.160 and 0.177. This suggests that at this level of forcing of piston engine optimal from the point of view losses of efficiency of working fluid is the isobaric turbocharging system.
