X-ray Flow Visualization

Multiphase flows include a dispersed phase mixed with a continuous fluid phase (gas-liquid, gas-solid, liquid-solid, liquid-liquid, gas-liquid-solid, and granular flows)

X-ray Radiography of Multiphase Flows

  • View internal hydrodynamics

X-ray Stereography of Multiphase Flows

  • Two synchronized and perpendicular X-ray projections through region of interest

X-ray Particle Tracking Velocimetry (XPTV)

  • Track 3D particle position and orientation in various multiphase and granular flows

X-ray Computed Tomography (CT) of Multiphase Flows

  • Provide 3D time-average phase distribution in gas-liquid, gas-solid, and granular flows
