ABSTRACT:
The invention relates to a fluid nozzle wherein the formation of eddy currents is reduced to a minimum in the area of laminar flow and the velocity of the fluid is increased to a maximum. This is accomplished by the use of a convergent nozzle wherein the fluid is accelerated and pressure is decreased, then directed over an atomizing body having a convex outer surface where the fluid is allowed to expand and increase its velocity with a further reduction in pressure. Protrusions in the form of a plate or other projections extend from the surface of the convex outer surface to produce fluid flow detachment, separation and high velocity fluid spraying. Adjustment means are provided whereby the axial distance between the nozzle orifice and the atomizing body can be varied according to the desired fluid flow patterns.
