Numerical
simulation of a complete gas turbine engine working with inlet wet injection
has been evaluated using computational fluid dynamic (CFD), the effects of water
droplet and injection rate on the compressor operation, engine combustion and
the turbine were studied. The results obtained in contrast with dry compression
unveil that, with minimum amount of water droplet and high water injection rate
(0.5% - 3.0%) their potential influence on the engine performance by boosting
the amount of inlet mass flow rate, raises compression and expansion pressure
ratio, uplift engine thrust and thermal efficiency through absorption of heat
and radiation intensity emission, decreases the relative specific fuel
consumption, combustion and turbine outlet temperature and cuts down the amount
of NOx production.
