Abstract

This paper demonstrates the validity of newly-developed the wall drag and form loss partitioning methods for dispersed flow. The wall drag partitioning method is proposed based on the equation of a solid/fluid particle motion. The bubble is faster than the water in a contraction while the former is slower than the latter in an expansion. The droplet is slower than the gas in a contraction while the former is faster than the latter in an expansion. In addition, this study shows that the existing form loss model predicts incorrectly the dispersed phase velocity. A new form loss computation method is proposed.
