Abstract
Rotodynamic machine for compressing a multiphase fluid comprising at least one gas phase and one liquid phase.The machine comprises at least one mobile wheel 6 rotating around an axis A-A′, mounted in a housing 1, and at least one fixed wheel 7 secured to housing 1. Mobile wheel 6 comprises a hub fitted with at least two blades 20 so as to form at least two channels delimited by hub 8, housing 1 and two of said blades 20. The channels have a centrifugal part.The length of one of the channels defined as the ratio of the volume of a channel to the maximum orthoradial area of said channel, measured in a plane perpendicular to the axis of rotation, ranges between 10 cm and 20 cm, and the ratio of the area of the largest orthoradial channel cross-section to the area of the smallest orthoradial channel cross-section is less than or equal to 3.
