The physics of the flow exiting a nozzle is very complex. Depending on the nozzle design, operating conditions and the surrounding gas flow, nozzle can produce from large ligaments to very fine droplets.

Using Volume of Fluid (VOF) based simulation, we can accurately model the flow exiting the nozzle and:

  • Study the effect of the surrounding fluid,
  • Determine the fluid sheet thickness,
  • Model liquid breakup,
  • Calculate resulted drop size.

Based in the above analysis, we recommend optimization for design and operating conditions.

The pictures bellow are a snapshot of simulations for determining the liquid sheet thickness performed for various atomizers.
