WebSep 22, 2024 · A good candidate to describe the SoC separation from graupel-ice crystal collisions is the relative diffusional growth rate (RDGR) theory (Baker et al., 1987; Mitzeva et al., 2005). According to this theory, the crucial factor for the SoC separation is the diffusional radius growth rate of the particles, dr/dt. The particle that grows faster by ... WebOnce the size of the critical nucleus exceeds that corresponding to n*þ d=2, at DG8¼DG* kT (see Figures 2.1 and 2.9), the probability that a chance thermal fluctuation will cause the loss of an atom that will initiate dissolution of the nucleus becomes sufficiently small so that the diffusional growth stage can be considered to have been ...
