Preliminary studies on jet flows from flat vane swirler: Effect of twist angle

In this present work, jet noise level measurements and flow field characteristics of coaxial flat vane Swirlers are investigated out experimentally to calculate the efficiency of the passive control regime. This induces swirl from six flat vanes with vane angles varying from 0֯ to 60֯. Experiments w...

Description
Summary:In this present work, jet noise level measurements and flow field characteristics of coaxial flat vane Swirlers are investigated out experimentally to calculate the efficiency of the passive control regime. This induces swirl from six flat vanes with vane angles varying from 0֯ to 60֯. Experiments were carried out using high-pressure open jet facility and images are captured through visualization technique. The results of noise levels and flow visualization were obtained for nozzle pressure ratios ranging from NPR 2 to NPR 5 and the same are compared between low and high swirler configurations.
