Asymptotic models for gas-liquid crystallization in two-film systems

Abstract : It is proposed to revisit the problem of gas - liquid crystallization in the framework of a two-film model and with the help of experimental data from two experimental systems. Preliminary quantitative discussion of the order of magnitude of different effects makes possible realistic simplifications in the theoretical models. In particular, the role of the interfacial film in the whole process is clearly defined. As previous researchers have done, a formulation in terms of moments of the crystal size distribution is used; however, instead of the numerical solution to the corresponding differential system, a general Procedure to express analytically the asymptotic behavior of the physical system is proposed. With this formulation, the influence of different parameters can be easily identified and validated on the available data from two experimental systems.
