Expt 9: Measurement of Droplet Size for an Air-Assist Atomizer

Aim of Experiment



  • To characterize the performance of air-assist atomizer in terms of droplet diameter and droplet size distribution.

  • Investigate the effects of gas and liquid mass flow rates on the droplet size.

  • Measure the average droplet size achieved in an air-assisted spray.

  • Study the droplet size distribution downstream of the atomizer orifice.
