A statistical model for predicting the particle distribution of an atomised powder in liquid mixture.
Synopsis A general stochastic model has been derived to show how a particulate solid phase dispersed in a liquid phase will be distributed through drops of the liquid when it is atomised into air or emulsified into an immiscible liquid. The process is applicable to the atomisation that occurs with an aerosol antiperspirant of the suspension type. The model accounts for the disproportionation of such systems by particle size that occurs during atomisation. It also provides a vehicle, in the case of an aerosol antiperspirant, for relating measurements taken in-flight by a laser imaging method with measurements of the constituent powder obtained by scanning electron microscopy to the amount and composition of material collected by the Hexhlet Elutriator, and shows these methods to be complementary.
