Influence of Mass Flow Rate on the Atomization Characteristics of Screw Conveyor Swirl Injectors

This study conducted cold flow experimental research on the influence of mass rate atomization characteristics screw conveyer swirl injectors in an opening environment. The Phase Doppler Particle Analyzer (PDPA) and high-speed photography were utilized to obtain data. results showed that greatly influenced establishment working injectors. design point selection exerted significant range performances a steady-state operation. Sauter mean diameter field continued decrease with increase rate. As distance injector exit increased, decrease, finally tended be stable. average particle obtained by current image-processing method was greater than PDPA; therefore, needs improvement.
