Experimental investigation of water distribution in two-phase zone during gravity-dominated evaporation [PDF]

open access: yes, 2017
We characterize the water repartition within the partially saturated (two-phase) zone (PSZ) during evaporation out of mixed wettable porous media by controlling the wettability of glass beads, their sizes, and as well the surrounding relative humidity ...

CFD analysis of evaporation heat transfer for falling films application

open access: yesEnergy Reports, 2022
Multi-effect desalination (MED) uses less energy and has a smaller footprint than other thermal desalination systems. The MED plant consists of cascaded horizontal-tube falling film exchangers (HFFE), offering improved heat transfer at lower liquid loads.

Spatially Resolved Monitoring of Drying of Hierarchical Porous Organic Networks [PDF]

open access: yes, 2016
Evaporation kinetics of water confined in hierarchal polymeric porous media is studied by low field nuclear magnetic resonance (NMR). Systems synthesized with various degrees of cross-linker density render networks with similar pore sizes but different ...

Trans-Planckian redshifts and the substance of the space-time river [PDF]

open access: yes, 1999
Trans-Planckian redshifts in cosmology and outside black holes may provide windows on a hypothetical short distance cutoff on the fundamental degrees of freedom.

Falling liquid films with blowing and suction [PDF]

open access: yes, 2015
Flow of a thin viscous film down a flat inclined plane becomes unstable to long wave interfacial fluctuations when the Reynolds number based on the mean film thickness becomes larger than a critical value (this value decreases as the angle of inclination

Flow and heat transfer characteristics of seawater falling-film evaporation on horizontal tubes

open access: yesDesalination and Water Treatment
Owing to their excellent heat transfer performance, falling film evaporators are widely employed in desalination and related fields. This study develops a three-dimensional, two-tube model based on the Volume of Fluid method to investigate the effects of

Modelling of multi-component droplet evaporation under cryogenic conditions

open access: yesOil & Gas Science and Technology, 2020
The vaporization of drops of highly vaporizable liquids falling inside a cryogenic environment is far from being a trivial matter as it assumes harnessing specialized thermodynamics and physical equations. In this paper, a multi-component falling droplet

Trapping ultracold atoms at 100 nm from a chip surface in a 0.7-micrometer-period magnetic lattice

open access: yes, 2017
We report the trapping of ultracold 87Rb atoms in a 0.7 micron-period 2D triangular magnetic lattice on an atom chip. The magnetic lattice is created by a lithographically patterned magnetic Co/Pd multilayer film plus bias fields. Rubidium atoms in the F=

Evaporation of a thin film: diffusion of the vapour and Marangoni instabilities [PDF]

open access: yes, 2004
The stability of an evaporating thin liquid film on a solid substrate is investigated within lubrication theory. The heat flux due to evaporation induces thermal gradients; the generated Marangoni stresses are accounted for.

Model development and simulating of a spinning cone evaporator : a thesis presented in partial fulfilment of the requirements for the degree of Master of Technology at Institute of Technology and Engineering, Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 2001
The idea of milk pre-concentration at the farm has attracted worldwide interest for many years. A new pilot-scale evaporator (called spinning cone evaporator), which can be operated on the farm and has a compact and efficient design, has been developed ...
