Abstract
A study is carried out for swirling flow of a fluid containing dispersed micro-bubbles (nominal size 80 μm in diameter). From experimental results the location of the stagnation point is found to be a strong function of the swirl ratio, but independent of the aspect ratio of the rotating pipe section when the actual position is normalized to the length of the section. It is also found from experimental results, with an aid of a numerical simulation, that a parabolic surface is formed by some larger bubbles which are caught in orbits of the rotating flow field. It is further verified that smaller-sized bubbles pass along limited stream lines.
