More Information
Summary:A turbo machine, particularly a pump for multiphase gas/liquid mixtures, is equipped with means for varying the pressure of a multiphase fluid by improving mixing of the gas and liquid phases. The device comprises a housing, a hub, a rotating shaft and at least two blades 6i, 6i+1 delimiting a flow channel for the multiphase fluid. One or more means are disposed inside one or more flow channels, these means being adapted to generate a turbulent zone inside the channels so as to mix the liquid and gaseous phases of the multiphase fluid. The means may produce a single flow helix, or two, contra rotating helices in the channel. The means may be beads or grooves of helical shape on the walls and the hub, or twisted blades at the upstream end of the flow channel which direct the flow into the required flow pattern to cause turbulence.
