ABSTRACT:
An air aspirating nozzle for propelling a stream of foam or a slurry of solid particulates to a target surface includes a stream shaping member within the nozzle to form a rotating, columnar stream of liquid and air that maintains a high degree of coherence over a considerable throw distance. The stream shaping member includes a cylindrical body portion held axially in place within the nozzle body by a plurality of vanes extending between the body portion and the inner nozzle wall. The vanes are arranged in a forward-raked attitude, and the vane surfaces are configured to impart a rotation to a fluid column passing through the nozzle.
