Abstract: Gas turbine engine efficiency can be increased by the improvements of the cooling air system. In this study, gas turbine preswirl cooling system is computationally analyzed using a validated three-dimensional quasi-steady model. In the first phase of the study, the system is analyzed with respect to different operating conditions, for understanding its behavior. In this part, the dependence of the discharge coefficient and the temperature drop on the inverse of the swirl ratio parameter are employed to characterize the system. In the second phase of the analysis, the possibilities of improving the system performance is investigated by implementing different modifications on the system geometry.
Keywords: Gas turbine cooling, Preswirl system, Discharge coefficient, Performance, CFD.
