| Abstract | Problems arising from natural moisture in the inlet air of gas turbine engines have been addressed. A study of open literature has identified two separate areas of concern: condensation taking place in the air intake, and performance changes arising from humidity effects on gas properties. A brief review of the elements of moist air was given. It was established that condensation depends on a complex combination of relative humidity, air temperature, inlet Mach number, and residence (dwell) time. Operational limits for humidity have been suggested. Two correction approaches for humidity effects on major engine parameters were investigated, one by Samuels and Gale and the other by Fishbeyn and Pervyshin. The correction factors of the two methods had the same trends and nearly the same magnitude for each parameter. It has been proposed that the correction system by Fishbeyn and Pervyshin be implemented for all gas turbine performance testing. These corrections can be of the order of 0.1 to 0.8% for high humidity test conditions. |
