FIELD: hydrodynamics; heating engineering. ^ SUBSTANCE: flow swirler can be used for processes of mixing and re-mixing of media, for handling heat exchange process between media and for transportation of different media with lower hydraulic resistance, particularly, different kinds of liquids, gases, different-phase media mixtures and pseudo-liquated powder-shaped media. Double-bladed fluid medium flow swirler has flat blades mounted in tube at angle to flow of liquid medium. Swirler has two similar swirlers mounted in tube with round cross-section. Any blade has profile in form of half-ellipse cut along its longer axis to two blades and achieved due to sloped section of tube, which section is made at angle to axis of tube being equal to angle of slope of blade's edge, formed by longer axis of ellipse, to axis of tube at mounting blades in tube. Angle of slope of blades' edge, formed by longer axis of ellipse, is inversely symmetrical to axis of tube and it equals to 5-85°. ^ EFFECT: reduced cost of manufactures; improved reliability of operation. ^ 2 cl, 5 dwg |
