  • FH-5 Fired Heater Research: Two-phase Flow in Vertical Serpentine Loop

    FH-5 Fired Heater Research: Two-phase Flow in Vertical Serpentine Loop

    November 03, 2017
    Adiabatic air-water studies were completed in a transparent vertical serpentine loop with a 12.7-cm internal pipe diameter and six vertical upflow and downflow sections with straight lengths exceeding 6 m. Liquid holdup in the vertical runs tends to dominate the overall pressure drop. This study focuses on flow visualization and pressure...
