Finite element analysis of multicomponent two‐phase flows with interphase mass and momentum transport
TLDR
In this article, the application of the finite element method to multiphase flow problems with interphase mass and heat transfer is described, and a general forinulation is used that determines the position of the interfacial boundary and allows for multiple solvents, differential volatilities and concentration-and temperature-dependent thermophysical properties.Abstract:
The application of the finite element method to multiphase flow problems with interphase mass and heat transfer is described. A general forinulation is used that determines the position of the interfacial boundary and allows for multiple solvents, differential volatilities and concentration- and temperature-dependent thermophysical properties. Species phase change and the dramatic volume change that acompanies interphase mass transfer make implementation of the theory challening, since these events lead to discontinuous velocities and concentrations at phase boundaries. These discontinuities are especially large in processes involving rapid evaporation or condensation. As examples we examine the effects of rapid drying on film and fibre formation of sol--gel materials, which are often laden with volatile species.read more

TL;DR: In this article, the authors present a review and critique of several methods for the simulation of the dynamics of colloidal suspensions at the mesoscale, focusing particularly on simulation techniques for hydrodynamic interactions, including implicit solvents (Fast Lubrication Dynamics, an approximation to Stokesian Dynamics) and explicit/particle-based (Multi Particle Collision Dynamics and Dissipative Particle Dynamics).

Stress development in drying coatings after solidification
TL;DR: In this paper, a theoretical model of diffusion and mass transfer, large shrinkage-induced deformation and stress, together with yielding and post-yielding viscous deformation, was developed to predict stress evolution in drying of polymer coatings after solidification.

TL;DR: The earliest commercial application of sol-gel technology was described in this paper, where a colloidal dispersion, or sol, of particles or polymers in a liquid is transformed into a rigid gel, which is a substance containing a continuous solid skeleton enclosing a continuous liquid phase.
