EFFECT OF SOLID PARTICLE CHARACTERISTICS ON SUSPENSION ATOMIZATION
ABSTRACT
Suspensions containing solid particles with different sizes and different bulk liquids have been atomized by means of a twin-fluid atomizer. From drop size analysis in the spray it was found that the solid particle size is the main influence on the drop size distribution. Consequently, the atomization of a suspension can be divided into different regimes as follows:
Atomization of suspensions with large particles, Dv50 > 50 mm. The drop size distribution in this range is bimodal, with two peaks (solid and liquid peaks). At lower values of (Weacro ґ ALR) the liquid diameter peak is controlled by the solid particle size and at higher values of (Weacro ґ ALR) it is controlled by the air stream velocity like the atomization of a pure liquid.
Atomization of suspensions with small particles, Dv50 < 50 mm. The drop size distribution is monomodal. The atomization mechanisms of suspensions containing fine solid particles are very similar to the atomization of the pure suspension liquid.
