Evolution convergent phase

MaePherson G. J. and Huss G. R. (2000) Convergent evolution of CAIs and chondrules evidence from bulk compositions and a cosmochemical phase diagram. In Lunar Planet. Sci. XXXI, 1796, The Lunar and Planetary Institution, Houston (CD-ROM). 

The convergence limits arc denoted in Fig. 10 as oo and oo. In contrast, the solid shows less discrete features. The condensed phase features are broader in width and shifted to higher photon energy. Both dominant features are due to spin-orbit splitting of the lowest core excitons, reflecting considerable changes in electronic structure from the gas to the condensed phase. This size dependent evolution of spectral features is shown... 

There has been considerable attention given to the development of 2 and 3-D numerical models to approximate the coupled two-phase mass and heat transport within unit cells, see [5, 7, 8, 15, 17, 22, 25, 29, 30, 38, 39, 37]. However, these approaches have either not fully resolved the multiphase flow, advecting the liquid as suspended droplets in the gas flow, or used isothermal models in which the vapor and liquid are treated as a combined mixture, or have experienced convergence difficulties for physically reasonable values of the parameters. The majority of the treatments are at steady-state, and none has treated the transient evolution of the free surface separating the two-phase and dry regions in the hydrophobic GDL.
