Sauter Mean Diameter Profiles of Droplets in a Continuous Spray Stream

Abstract:

In this study, a modified starch solution was heated upto 80°C and continuously sprayed into ambient air with an axi-symmetric full cone nozzle operated at two different load pressures 3 and 5 bar. The generated sprays were characterized for axial Sauter Mean Diameter (SMD) by using a non-intrusive Phase Doppler Anemometry (PDA) technique. A monotonic decrease in SMD downstream to the nozzle exit was noticed at 5 bar load pressure. At 3 bar load pressure, initially, SMD decreased between 10-20 mm downstream, then increased between 20-40 mm and finally reached to its lowest values at 100 mm downstream. Overall, the SMD measured at 3 and 5 bar load pressures was decreased from 99 to 66 μm and 85 to 57 μm respectively after moving 100 mm downstream.
