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.
A nozzle for producing a randomly directionally unstable liquid discharge comprising a body defining therein a chamber having a liquid inlet thereinto and a liquid outlet duct therefrom to the exterior of the body, the liquid flow area of the inlet to the chamber being at least as great as the minimum liquid flow area of the outlet duct, the liquid inlet to the chamber being defined for flow of liquid into the chamber in a direction substantially opposite to the direction of liquid flow from the chamber through the outlet duct, the chamber being defined cooperatively with the inlet and the outlet duct for substantially linear flow of liquid through the outlet duct during operation of the nozzle, the outlet duct having an straight throat portion of constant diameter communicating from the chamber to a flared section portion of the duct, the duct throat portion having a ratio of length to diameter in the range from about 1/3 to about 18, the diameter of the duct second portion increasing proceeding along the duct from the chamber from a diameter equal to that of the duct throat portion, the angle of flare of the duct second portion relative to the axis of the throat at the intersection of the duct throat and second portions being at least 2.degree. and no greater than 6.degree..
