Abstract: In some examples, a fluid nozzle includes an aperture comprising a first lobe that is shaped as an ellipse, and a second lobe that has a non-circular shape and has a different size than a size of the first lobe. The fluid nozzle further includes protrusions between the first and second lobes extending inward and forming a throat between the first and second lobes.

Abstract: A method to control puddling on a fluid dispense head, comprising limiting the height of a puddle of fluid over a fluid dispensing nozzle while simultaneously limiting the spread of the puddle laterally away from the nozzle.

Abstract: An inkjet nozzle includes an aperture with a noncircular opening substantially defined by a polynomial equation. A droplet generator is also described which includes a firing chamber fluidically coupled to a fluid reservoir a heating resistor and a nozzle. The nozzle includes an aperture forming a passage from the firing chamber to the exterior of the droplet generator through a top hat layer. The nozzle is defined by a closed polynomial and has a mathematically smooth and mathematically continuous shape around aperture's perimeter wall, with two protrusions extending into the center of the aperture.
