dc.description.abstractThis article focuses on a radial preswirler system using CFD, and the effect of different parameters such as the number and the angle of the holes at the preswirl nozzle exit, and the diameter of the preswirl nozzles have been investigated. Three-dimensional steady CFD simulations on a 22.5deg sector model showed a non-monotonic trend of swirl velocity at the inlet of the receiver holes and associated flow angles when different preswirl nozzle configurations are tested. Sudden rise in swirl ratio can be attributed to interactions of adjacent nozzle jets. Due to this flow feature swirl velocities are enhanced up to a certain angle where the interaction starts to diminish. Free vortex assumption in between nozzle exit and receiver inlet holds, as angular momentum of the nozzle jet is much more dominant compared to torques exerted by stator surfaces.
