... oil flows are actuated for a wide range of phase fractions and relatively low mixture velocities by using a multi-nozzle inlet with 1056 nozzles. High-speed visualisations show that the flow remains fully dispersed downstream the inlet only at high mixture velocities. At low velocities a continuous...
