| Abstract | (a=1.9x10-4/D, c=0.14/D) , where D is the inner diameter of the suction pipe in the unit of meter, H the submergence, Fr the Froude number (= V12/gH), and Ro the rotational Froude number (= C2oo/gH3). The subscript n on Ro and Fr denotes the onset correlations derived independently from the relation between Ro and H/D and the relation between Fr and H/D. From visual observation and theoretical consideration, it was found that the above two criteria come from the fact that the onset conditions are dominated by the following two factors : whether the air core formed by vortex reaches the pipe, and whether the water flow in the suction pipe is fast enough for the flow to draw bubbles downward. By combining the two onset criteria into single correlation and comparing it with experimental data, the following correlation was derived, |
