Investigation on the Onset of Gas Entrainment by Experimental Simulation of Two Side Branches of PHWR Header Using Air and Water

vortex free, critical height, single discharge, dual discharge, and smooth stratifiedAbstract
An experimental investigation has been conducted to determine the vortex free critical height during single
discharge and dual discharge from the smooth stratified air-water region through side branches mounted on a circular
surface. The branches are of 9 mm internal diameter and oriented at 00 and 1800
. The experimental data are generated
for branch Froude number in the range of 6.4 to 27.5. Both the branches are kept at equal Froude number. The results
are compared with existing empirical and theoretical correlations. Experimental based correlations are developed
relating critical height, branch diameter and Froude number
