ABSTRACT:
Methods and apparatus are provided for extending the effective length of a jet of fluid exiting a nozzle. An elongated jet extension member extends substantially axially outward from a nozzle outlet, and the jet of fluid flowing along and around the extension member tends to cling to the extension member thus decreasing the angle of divergence of the fluid jet.
