Evaporation from porous surfaces into turbulent airflows: Coupling eddy characteristics with pore scale vapor diffusion

E Haghighi, D Or - Water Resources Research, 2013 - Wiley Online Library
Evaporative fluxes from terrestrial porous surfaces are determined by interplay between
internal capillary and diffusive transport, energy input, and mass exchange across the land‐
air interface. Turbulent airflows near the Earth's surface introduce complex boundary
conditions that affect vapor, heat, and momentum exchange rates with the atmosphere. The
impact of turbulent airflow on evaporation from porous surfaces was quantified using surface
renewal theory coupled with a physically based pore scale model for vapor transfer from …

[PDF][PDF] Evaporation from porous surfaces into turbulent airflows

E Haghighi - 2015 - research-collection.ethz.ch
Evaporation from porous media is a ubiquitous process appearing in many applications from
soil and hydrology to biological and food processing, thermally enhanced oil recovery,
drying of textiles and granular materials, and many other engineering applications.
Evaporation is a key process in land-atmosphere mass and energy exchange driving the
hydrological cycle and affecting energy balance of terrestrial surfaces. Evaporative drying of
terrestrial surfaces involves coupled heat and mass transfer and depends on hydraulic …
