Based on the simultaneous measurements of drop she and velocity, the experimental bivariate probability density function of their occurrence was determined over 16 sample locations in a solid-cone spray. The function was plotted in contour maps, indicating some bimodality of the size-velocity distributions. A composed form of dual logarithmic-normal distribution functions was proposed to describe the experimental function. It is concluded that the proposed function is satisfactory, since the coefficient of correlation between the calculated and the observed probability densities is close to 1. In addition, the evaluated means of drop size and velocity show good agreement with the measured values.
