Abstract
Provided is a fluidic oscillator circuit for a nozzle assembly configured to generate oscillating sprays of fluid from an outlet of the nozzle assembly and to improve spray performance of fluid having low temperatures or high viscosity. In one embodiment, provided is an interaction region for a fluidic oscillator circuit that includes an apex protrusion shaped to assist with generating vortices within the interaction region. In another embodiment, provided is an interaction region for a fluidic oscillator having a power nozzle that includes at least one finger protrusion that lengthens the power nozzle to create jets of fluid in the interaction region that are less diffused to improve cold performance of the fluidic oscillator circuit.
