Two Fluid (Pneumatic) Nozzle Mean Droplet Diameter Calculator

This tool calculates the mean diameter D32 of droplets resulting from atomisation of a liquid using a two-fluid (pneumatic) nozzle.

Type the required values to get the droplet mean diameter:

Surface Tension (σ, N/m)

Atomising Gas Density (ρg, kg/m3)

Velocity (vo,m/s)

Liquid Flow Rate (L, kg/s)

Gas Flow Rate (G, kg/s)

Nozzle Diameter (Dnozzle, m)

Droplet Mean Diameter D32 (µm)
