摘要：Experiments were performed on the breakup of water droplets in a coaxial twin-fluid air-blast atomizer by a high-speed gas stream.With the measurements of Sauter mean diameter(SMD)distributions at a downstream distance of the atomizer,the droplet size was found first to decrease,reaching a minimum,and then to increase monotonically with the downstream distance.Correlation of Lc where the minimum droplet size appeared as a function of aerodynamic Weber number and liquid Reynolds number was analyzed.The growth rate of droplet size passes by Lc downstream increased with increasing water velocity,and the relationship between SMD and x/Dg accurately reflected the increasing trend of droplet size.
Experiments were performed on the breakup of water droplets in a coaxial twin fluid air-blast atomizer by a high-speed gas stream, With the measurements of Sauter mean diameter （SMD） distributions at a downstream distance of the atomizer, the droplet size was found first to decrease, reaching a minimum, and then to increase monotonically with the downstream distance. Correlation of Lo where the minimum droplet size appeared as a function of aerodynamic Weber number and liquid Reynolds number was analyzed. The growth rate of droplet size passes by Lc downstream increased with increasing water velocity, and the relationship between SMD and x/Dg accurately reflected the increasing trend of droplet size.
