Abstract: Systems, devices, and methods for fluid dispensing nozzles are described. Various implementations include a fluid dispensing nozzle including an inlet section which defines an inlet channel with a first diameter, and a restriction region which defines a restriction channel fluidically coupled to the inlet channel. The restriction channel extends along a first predetermined length and has a second diameter that is smaller than the first diameter. The nozzle includes an expansion chamber which defines an expansion channel fluidically coupled to the restriction channel. The expansion chamber has a trumpet shape with a maximum diameter at an outlet of the expansion chamber. The maximum diameter of the expansion chamber is greater than the first diameter; and nozzle includes a diffuser plate positioned at the outlet of the expansion chamber. The diffuser plate includes a plurality of openings and a mesh insert that is disposed across the plurality of openings.
