Drop size distribution in emulsions O/W stabilized by nonionic emulsifier; Description of distribution by empirical relations

Abstract

Here is analysed how suitable are the most frequently used empirical relations for description of drop size distribution. On a representative set of emulsifying experiments is demonstrated how suitable in the three-parametric logarithmic normal distribution according to Cohen and distribution according to Espenscheid-Kerker-Matijević. For these functions are proposed methods of parameter estimation suitable for their determination from the random sample of emulsion droplets. The fittnes of testing functions is discussed briefly.
