Component Specifications

Definition
The swirl chamber is a cylindrical or conical cavity within a spray nozzle where fluid enters tangentially through inlet ports, generating controlled rotational velocity. This centrifugal force creates a thin liquid film that exits through an orifice as a hollow-cone spray with defined droplet size distribution. Key parameters include chamber diameter, length, inlet geometry, and surface finish, which collectively determine spray angle, flow rate, and atomization quality.
Working Principle
Fluid enters the swirl chamber through tangential inlets, creating vortex motion. Centrifugal force pushes fluid outward, forming an air core at the center. As the rotating fluid exits through the discharge orifice, it expands into a conical sheet that breaks into droplets due to aerodynamic instability and surface tension effects.
Materials
Stainless steel (AISI 316L), brass (C36000), ceramic (alumina), or engineered polymers (PTFE, PEEK) depending on corrosion resistance, wear requirements, and temperature ranges.
