Drop size distribution Gaussian

Cumulative drop size distributions can be plotted conveniently on linear or log probability paper. A straight line on linear or normal probability paper means that the drop sizes follow a normal or Gaussian distribution. If data form a straight line on log probability paper, the distribution is referred to as lognormal. 

Delichatsios and Probstein (D4-7) have analyzed the processes of drop breakup and coagulation/coalescence in isotropic turbulent dispersions. Models were developed for breakup and coalescence rates based on turbulence theory as discussed in Section III and were formulated in terms of Eq. (107). They applied these results in an attempt to show that the increase of drop sizes with holdup fraction in agitated dispersions cannot be attributed entirely to turbulence dampening caused by the dispersed phase. These conclusions are determined after an approximate analysis of the population balance equation, assuming the size distribution is approximately Gaussian.
