Droplet Size Distribution and Liquid Volume Concentration in a Water Spray: Predictions and Measurements
Abstract
A water spray, from a twin-fluid atomizer, was studied at different air temperature and at atmospheric pressure. The Sauter Mean Diameter, D32, and the droplet volume distribution were measured at four different distances from the injector. An optical method was used to measure droplet sizes. Predictions of the Sauter Mean Diameter, liquid volume concentration and droplet size distribution were also evaluated. The influence of the air velocity, air temperature and of the water flow rate in the spray S.M.D. and in the liquid volume concentration at different distance from the injector have been measured. The predictions showed good agreement with experimental results.
