Abstract:
... In this study, we present experimental and theoretical analyses of evaporating a double-emulsion drop resting on a substrate. Multistage evaporation of the outer and inner droplet is witnessed. The complete evaporation of the outer drop and the initialization of the inner drop evaporation demonstrate an interesting transition dynamics. After the apparent completion of evaporation of the inner phas ...

Abstract:
... It was experimentally shown that a depinning force of a receding droplet on a micropillared superhydrophobic surface has an apparently linear correlation with the maximal three-phase contact line attainable along an actual droplet boundary. However, the experimental observation has not yet been supported by any theoretical basis or analysis. This study establishes an analytical model that theoreti ...

It can provide new insights on liquid pattern control through manipulating droplet solutions. We show the pronounced transitions of wetting for surfactant solution droplets drying on a micropyramid-patterned surface. At low initial surfactant concentrations, ...

Abstract:
... Evapoporometry (EP) determines the pore-size distribution (PSD) based on the Kelvin equation that relates the evaporation rate of a volatile wetting liquid to the pore diameter. EP offers several advantages relative to other PSD characterization methods. EP is adapted here to characterize only the continuous pores rather than all the pores. This adaptation involves sequentially injecting a volatil ...

However, in a practical cycle, pressure losses will occur in heat exchangers and pipes. The pressure losses can influence the evaporating and condensing process and further influence the overall performance of ORC. In this study, the flow loss coefficients of evaporator and condenser a ...

The mass spectra show a very strong odd–even effect, consistent with a low degree of scrambling of the hydrogen bound to water and to the ammonia. The relative evaporation rate constant for light water was almost twice the one for heavy water, wi ...

We analyze the effect of evaporation on expanding capillary flow for losses normal to the plane of a two-dimensional porous medium using the potential flow theory formulation of the Lucas–Washburn method. Evaporation induces a finite steady state liquid flux on capillary flows into fan-shaped domains which is significantly greater than the flux into media of constant cross section. We introduce th ...
