| 摘要 |
<p>The present invention discloses an apparatus (2) for generating a two-phase flow (BJF) comprising à first tube (4) for directing a first fluid flow (AF), a second tube (8) for directing a second fluid flow (IWF) and, a third tube (6) for directing a third fluid flow (EWF), wherein the first, second and third tube (4, 6, 8) are aligned essentially parallel to each other, said first tube (4) has length to diameter factor larger than 10 and is disposed at least partially and essentially symmetrically within the second tube (8), said second tube (8) extends over the orifice of the first tube (4) by a distance of a multiple of its diameter as seen in the flow direction of the first fluid flow (AF), and the second tube (8) is aligned with the third tube (6) which extends over the orifice of the second tube (8), whereby the first, second and third tube (4, 6, 8) have respective first, second and third fluid supply means (10, 12, 14) disposed upstream controlling the third fluid flow (EWF), the second fluid flow (IWF) and the first flow (AF) separately.</p> |
