Abstract :Numerical simulation of a complete gas turbine engine working with inlet wet injection has been evaluated using computational fluid dynamic insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(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.
