Within the chamber 21 the combination of the
rotating motion of the air column and the action
of the jets causes a very thorough mingling of
the air and the water without substantial eddy
currents. The particles of water are thrown out
wardly against the interior walls of the casing
or upon the baiile 25, thus furnishing the sup-ply
of water for the sheet which falls from the edge
