Investigation of the evaporation in the boundary layer

open access: yesИзвестия высших учебных заведений: Проблемы энергетики, 2020
THE PURPOSE. Consider a stationary diffusion problem when a pure liquid evaporates from a flat surface of evaporation into a laminar boundary layer of a forced gas flow (in the absence of deepening of the evaporation surface and wave formation on it) at ...

Evaluation of three energy balance-based evaporation models for estimating monthly evaporation for five lakes using derived heat storage changes from a hysteresis model

open access: yesEnvironmental Research Letters, 2017
The heat storage changes ( Q _t ) can be a significant component of the energy balance in lakes, and it is important to account for Q _t for reasonable estimation of evaporation at monthly and finer timescales if the energy balance-based evaporation ...

Water footprint of the Sobradinho hydropower plant, Northeastern Brazil

open access: yesRevista Ambiente & Água, 2018
Hydroelectricity is responsible for the greatest fraction of the electric energy generated in Brazil. The water footprint of hydropower plants (WFP) is an important indicator of the sustainable and efficient use of water resources.

Model of the meniscus of an ionic liquid ion source. [PDF]

open access: yes, 2008
A simple model of the transfer of charge and ion evaporation in the meniscus of an ionic-liquid ion source working in the purely ionic regime is proposed on the basis of order-of-magnitude estimates which show that, in this regime, _i_ the flow in the ...

Deposit Growth in the Wetting of an Angular Region with Uniform Evaporation

open access: yes, 2005
Solvent loss due to evaporation in a drying drop can drive capillary flows and solute migration. The flow is controlled by the evaporation profile and the geometry of the drop. We predict the flow and solute migration near a sharp corner of the perimeter
