Abstract: A fluidic geometry to produce uniform oscillating sprays is described. The geometry can be embodied as an insert, housing, or system in which an inlet feeds an interaction chamber. A major island is disposed at the upstream end of that chamber so as to create two power nozzles that are positioned off of the centerline axis and downstream of the major island. A minor island is also disposed within the interaction chamber, but remains spaced apart and downstream of the major island so as to define an exchange channel. The exchange channel creates an inertance effect that can be controlled and adjusted so as to provide the desired oscillating spray fan produced by the geometry. This arrangement exhibits consistent cold and high temperature performance for a range of fluid compositions and operating conditions.
