CONDITIONING AND TREATING A FLUID FLOW

摘要

A device for conditioning a fluid flow in a duct around an irradiating element such as an UV element, comprising means for generating multiple vortices in a fluid flow wherein the generating means comprises a flow conditioning body with an orifice, whereby the orifice shape is defined by an inner edge of the body arranged such that the distance from the centre of the orifice to the inner edge of the body varies substantially sinusoidally around at least part of the inner edge of the body.
