Summary:
This study experimentally investigated crosssectional measuring points necessary for point correlation dimension analysis of fully developed slug flow. Applying an optimal delay time reconstruction method and a point correlation dimension method to cross-sectional void fraction time series greatly improves the reliability of analyses. Results show that nine-point averaging is sufficient for a broad range of airflow rates. When the air flow rate is low, one-point measurement, except in the area near a pipe wall, yields reliable results.
