Measurements of the pressure drop and liquid hold up in a gas flow with wet walls were carried out on a vertical pipe at NTNU Multiphase Flow Laboratory. The experiments were performed as a dry-up process, where an initial liquid film becomes thinner with time as it is removed by gas flow. Quick closing valves were used to measure the liquid holdup in the vertical section. Two data sets using Air-Water and Air-Mineral oil were obtained. A significant increase on pressure drop with small amounts of the liquid holdup was observed. Pressure gradient and holdup behavior were reproduced quite well by commercial flow simulators but the flushing time showed discrepancies.
