Comment on "Crystallization of supercooled liquids: Self-consistency correction of the steady-state nucleation rate" by Abyzov et al., Entropy 2020, 22, 558

It is shown that in the growth region (above the critical nucleation size) the transient distributions obtained numerically from the Becker-Doring equation (BDE) by Abyzov et al., Entropy 2020, 22, 558, are in accurate correspondence with the matched asymptotic (singular perturbation) solution by Shneidman, Sov. Phys. Tech. Phys. 1988, 33, 1338. The solution is unmodified by "self-consistency" corrections which affect only the steady state rate. Sensitivity of the results to selection of a specific form of the BDE (the "nucleation model") also is briefly discussed.
