.... In addition, the study describes ways to validate simulations of multiphase flows with heat and mass transfer. Validating techniques compare simulation results against planar interface evaporation (Stefan type problems) and spherical bubble growth. Implications of numerical validation in the generated...

.... Vapor pressure was introduced as an important variable. Since vapor pressure is the force per unit area resulting from molecular collisions, and osmosis occurs with liquid on both sides of the membrane, I proposed that free molecules must exist in pure liquids and solids. osmosis evaporation...

In this paper, a di-electric heating method is presented that combines electrical standing wave voltage amplification with porous interface (carbon foam) materials to intensify water evaporation. The system targets the di-electric loss tangent of the aqueous...

... effects in a diverging electric field. During the drying process, in the presence of the DEP force, the vapor phase is extracted away from the porous medium, which results in an increase of the evaporation rate and a decrease of the sample surface temperature. This paper extends previous experimental...

... Abstract In the present study, a lumped capacitance, 0-D model was developed for simulating thermal runaway of Li-ion battery cells. The model accounts for multi-mode heat transfer, physics associated with gas generation, evaporation of liquid electrolyte, and venting of gases out of the cell...

The DPD simulation includes the DLVO forces between the particles, their interaction with the substrate surface, Stokes drag, Brownian...

... The heat transfer of a water spray impinging upon a surface in a very low pressure environment is of interest to cooling of space vehicles during launch and re-entry, and to industrial processes where flash evaporation occurs. At very low pressure, the process occurs near the triple point...

... The evaporation of sessile water droplets has been investigated numerically in this paper. A numerical model based on the quasi-stationary assumptions is established for describing the evaporation dynamics. Droplets are assumed to be pinned and axisymmetric on a substrate during the evaporation...
