ABSTRACT:
A liqud discharge nozzle for producing a randomly directionally unstable liquid discharge characteristic includes a body having a chamber therein. An inlet is provided to the chamber. An outlet duct is defined from an end of the chamber to the exterior of the body. The chamber, the inlet and the outlet duct are cooperatively related so that the direction of liquid flow into the chamber is substantially opposite to the direction of liquid flow from the chamber and so that the liquid flow characteristic through the outlet duct is linear. The outlet duct has a straight constant diameter first portion communicating from the chamber to a flared second portion of the outlet duct. The duct first portion has a ratio of length to diameter in the range from about one-third to about 18. The diameter of the duct second portion increases proceeding away from the chamber from an initial diameter essentially equal to that of the duct first portion.
