Daughter size distribution model used by Laakkonen et al. (2006). Note that it must be multiplied by the number of daughter particles (2). Also, the coefficient C4 needs to be set to the value of 2 as to ensure number and mass conservation following Kumar and Ramkrishna (1996). Also the internal coordinate was changed to particle volume, which gives. More...
