Research on Swirl-Core Nozzle with Adjustable Spray Angle Based on Vortex Theory

Abstract:

Article Preview

According to Vortex Theory, the fluid flow in a swirl-core nozzle was analyzed, and an equation of spray angle was presented. The fluid in this nozzle was simulated by Volume of Fluid Model through CFD. The fluid dynamic simulation results show that diameters of nozzle opening and swirl chamber, area of spiral groove, and helix angle of the spiral groove affect the spray angle. There are optimum structural parameters for a swirl-core nozzle, and the spray angle can be adjusted by changing the depth of the swirl chamber with fixed structural parameters of the nozzle.
