Abstract (en)
[origin: EP0468877A1] The present invention relates to a compression device for a multiphase fluid comprising a liquid phase and a gaseous phase, and its use. The device comprises a housing (1), a pulse generator having an inlet section and an outlet section, the said pulse generator comprising a hub having an axial symmetry (28) of axis Ox and a number n of blades rotating about the said axis, these blades having a leading edge (C1; C2) and a trailing edge (C'1; C'2). The said fluid enters into the said pulse generator through the inlet section (41) and emerges therefrom through the outlet section (42), the said axis being aligned in the direction of advance of the said fluid, the number of rotating blades (29, 30) being equal to or greater than 2. It is characterised in that it comprises at least one duct or passage defined by two successive blades (29, 30), of which the orthoradial cross section S(x) is in the form, to within 5% and preferably to within less than 3%: S(x) = a x2 + b(c -x2)1/2 + d over at least part of its length, the said part lying between two orthoradial planes, the variable x corresponding to the abscissa according to the said axis, the origin of which largely corresponds to the radial plane passing through the leading edge of the said blades, the said radial planes defining the said part having as its abscissa x1 and x2, a, b, c and d being parameters. <IMAGE>
