Area of Science:

  • Fluid dynamics
  • Surface tension phenomena

Background:

  • Droplet formation is governed by the Young-Laplace equation.
  • Nozzle geometry is a key factor in droplet size control.

Purpose of the Study:

  • To investigate the effect of nozzle geometry on fluid droplet size.
  • To determine if non-circular nozzles can produce smaller droplets than circular ones.

Main Methods:

  • Analyzing solutions to the Young-Laplace equation.
  • Comparing droplet volumes produced by circular and triangular nozzles at critical pressure.

Main Results:

  • Circular nozzles produce the largest droplets at critical pressure.
  • Triangular nozzles with stretched corners reduce droplet volume by up to 18%.

Conclusions:

  • Nozzle shape significantly impacts droplet size.
  • Non-circular nozzle designs offer a method for producing smaller fluid droplets.
