Component Specifications

Definition
The hub or centerbody is the core structural element of a swirl vane assembly, typically cylindrical or conical, designed to securely mount and radially position multiple vanes. It ensures precise angular alignment and mechanical stability while withstanding centrifugal forces, pressure differentials, and thermal stresses in fluid systems. This component creates the central axis around which vanes induce rotational flow patterns.
Working Principle
Acts as the mounting platform and geometric reference for swirl vanes, maintaining their radial position and angular orientation to impart controlled swirl or vortex motion to fluids (gases or liquids) passing through the assembly. The hub's geometry influences flow characteristics by defining vane attachment points and central obstruction effects.
Materials
Typically manufactured from corrosion-resistant alloys (e.g., stainless steel 304/316, aluminum 6061-T6), high-strength composites, or engineered polymers (PEEK, PTFE) depending on temperature, pressure, and chemical exposure requirements. Surface treatments may include anodizing, plating, or coatings for wear resistance.
