Rosin-Rammler function model

A hammer crusher was designed to liberate the coating from the plastic substrate. The size distribution of particles was analyzed and could be described by the Rosin-Rammler function model (26-28). 

A 3D liquid spraying is modeled by introducing 20 spatial droplet streams into the computational domain, as shown in Figure 10.5. In turn, each droplet stream is represented by 10 injections of different droplet diameters minimum and maximum diameters are 10.0 and 138.0 pm, whereas the intermediate droplet sizes are calculated by applying Rosin-Rammler distribution function with 70.5 pm of droplet average size as given by Equation 10.37. 

A number of model distribution functions exist, some of which fit the size distributions of many powders quite well. The model functions used most frequently are the normal (or Gaussian ) distribution, the log-normal distribution and the Rosin-Rammler distribution (Allen, 1990). These are given in Appendix 2.B for reference. The latter two can be fitted particularly well to the volume distributions of a wide range of powders. The Rosin-Rammler distribution was used to produce Figures 2.3.3 and 2.3.4.
