整流器

A flow straightener is a precision-engineered component installed in fluid conveyance systems to condition flow by eliminating swirls, vortices, and non-uniform velocity profiles. It typically consists of an array of parallel channels or honeycomb structures that redirect fluid particles into parallel streamlines, ensuring laminar or near-laminar flow downstream. This component is critical for accurate flow measurement, efficient mixing, and stable process control in industrial applications.

The flow straightener operates on the principle of flow conditioning through flow resistance and redirection. As fluid enters the device, its cross-sectional area is divided into multiple small channels (typically hexagonal, square, or circular). These channels have high length-to-diameter ratios that force fluid particles to align with the channel walls, dissipating turbulent kinetic energy through viscous friction. The parallel arrangement converts rotational momentum into linear momentum, producing a uniform velocity profile with minimal pressure drop when properly designed.
