Feasibility Of X-Ray Scattering For Tracer-Free Liquid-Phase Thermometry For Multiphase Flows

The feasibility of liquid temperature measurements using X-ray scattering is investigated for liquids with varying properties (water, ethanol, and n-dodecane) on beamline 7-BM at the Advanced Photon Source at Argonne National Laboratory. The temperature is inferred through the change in the scattering pattern from the liquid as a function of temperature using partial least squares regression. An accuracy of similar to 98% or higher was achieved enabling measurements for a wide range of applications.
