Relative factors between the gamma distribution and monodisperse distribution for the condensation and evaporation rates (left) and collisional growth rates (right). The vertical dotted line shows the ν =1 values, denoting an exponential distribution (Paper I). As ν → ∞, the rates tend towards the monodisperse limit. However, for coagulation in the Kn ≫ 1 regime, assuming H = 0.85 does not recover the monodisperse limit, even for large ν, while a value of H =1/√2 does recover the monodisperse limit.
