Abstract:
1. An apparatus for atomizing a fluid, comprising an atomizing nozzle assembly, wherein the atomizing nozzle assembly comprises: a spray applicator enclosure having a fluid entry zone, a flow shape profiler region comprising a tapered profile to provide flow acceleration from said fluid entry zone to an outlet, a transducer having a portion located within the flow shape profiler region, and a cavitation enhancer module located adjacent to the outlet of the flow shape profiler region, wherein the cavitation enhancer module comprises a residence modulation zone and a tapered flow modulation zone fluidly coupled downstream of the residence modulation zone, wherein the residence modulation zone comprises a backward facing step region, wherein the apparatus is configured such that fluid can enter the fluid entry zone to the flow shape profiler region, and the cavitation enhancer module.
