Spraying Liquid Using Pneumatic Nozzle for Suspension Fuel

  • Published:
Journal of Engineering Thermophysics Aims and scope

Abstract

Characteristics of gas-droplet flow created by spraying a liquid using an advanced pneumatic nozzle for suspension fuel were studied experimentally. The measurements were made using the shadow photography method. On the example of water, the disperse composition of the gas-droplet flow, jet expansion angle, and flow structure stability were determined for different regimes. It was shown that most droplets were less than 10 \(\mu\)m in size. The disperse composition of the flow remained unchanged for a wide range of operating parameters. The nozzle designed generates droplets of a size sufficient for efficient combustion of suspension fuel under real conditions.
