dc.description.abstract | Pre-swirler is classified into the Tangential On-Board Injection (TOBI) type and the Radial On-Board Injection (ROBI). The TOBI type has a spatial margin from the duct inlet to the pre-swirler inlet, it is possible to install an additional guide system that can create the pre-swirl effect, maximize system performance. Whereas, the ROBI type has the advantage of making the pre-swirl effect even when the installation space of the secondary cooling air system is insufficient. In this study, two types of the pre-swirl system performance were compared by selecting the ROBI type with the same swirl ratio and mass flow rate as the TOBI type. When the swirl ratio of two types were the same, the temperature drop was not significantly different, but the discharge coefficient of the ROBI type was 8.1% higher than the TOBI type. When the mass flow rate of the two types were the same, the temperature drop of the TOBI type was 13.8% higher than the ROBI type and the discharge coefficient of the TOBI type was 4.1% lower than the ROBI type. | - |
