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 wheelrotating around an axis A-A', mounted in a housing, and at least one fixed wheelsecured to housing. Mobile wheelcomprises a hub fitted with at least two bladesso as to form at least two channels delimited by hub, housingand two of said blades. 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.
