| 摘要 | A fluid mixing device comprising: wall structure defining a chamber (6) having a fluid inlet (1) and a fluid outlet (4) disposed generally opposite the inlet; said chamber being larger in cross-section than said inlet at least for a portion of the space between said inlet and outlet; flow separation means (2) to cause a flow of a first fluid wholly occupying said inlet to separate from said wall structure upstream of the outlet; wherein the distance between said flow seaparation means and said outlet is sufficiently long in relation to the width of the chamber for the separated flow to reattach itself asymmetrically (22) to the chamber wall structure upstream of the outlet and to exit the chamber through the outlet asymmetrically (23), whereby a reverse flow (26) of said first fluid at said reattachment and/or a flow (24) of a second fluid induced from the exterior of the chamber through said outlet swirls in the chamber between said flow separation and said reattachment and thereby induces precession of said separated/reattached flow, which precession enhances mixing of the flow with said second fluid to the exterior of the chamber. |
