    Notes: Surface tensions of several binary mixtures are computed using the gradient theory of inhomogeneous fluids. The interfacial influence parameters are determined from mixing rules and pure fluid experimental tensions. A comparison of the compositional dependence of the predicted and experimental tensions indicates that the best results for nonpolar hydrocarbons are obtained from a geometric mixing rule for the influence parameter. Predicted tensions vs. composition for nonpolar systems are in excellent agreement with experiment, generally lying within 2% of observed data. Predictions are poor for alcohol solutions.

    Notes: The Isotherm Migration Method of numerically analyzing conduction with phase change is modified to handle surface and external resistances, appearance, and propagation of successive fronts into slabs of composite material of one or more constituents finely dispersed in a matrix, different components transforming at different temperatures. Procedures are developed for selecting temperature intervals between isotherms, initially locating isotherms by means of analytical approximations to the earliest stages, and thereafter inserting and removing isotherms as appropriate, particularly when each component gives rise to a separate front.

    Notes: The Modified Isotherm Migration Method (MIMM) is developed for solving one-dimensional Stefan-type problems of multifront propagation in slabs, cylinders and spheres with a boundary condition of the third kind (radiation-type boundary condition). The method is illustrated for all three geometries with applications to the thawing of ice and to the freezing of a 50-50 dispersion of tetradecane in water, a system in which two freezing fronts propagate simultaneously.
