Abstract
The effects of pre-dilution devices and mixing tubes on overall initial dilution between discharge point and surface are considered. A novel shape of tube is studied in which the three dimensional jet is converted to a two dimensional flow through a slot at the end of the mixing tube. This is shown experimentally to be generally similar but perhaps slightly better than traditional cylindrical mixing tubes.
