Evaporation

From Thermal-FluidsPedia

Evaporation processes generally occur from liquid films, drops, and jets. Films may flow on a heated or adiabatic surface as a result of gravity or vapor shear. Drops may evaporate from a heated substrate, or they may be suspended in a gas mixture or immiscible fluid. Jets may be cylindrical in shape or elongated (ribbon-like).

• Basics

Classification and Criteria of Evaporation.

• Film Evaporation

Adiabatic walls, classical nusselt evaporation, laminar falling film with surface waves, turbulent falling film, surface spray cooling and heated wall.

• Direct contact evaporation

Liquid droplet in a hot gas and liquid jet in a pure vapor.

• Evaporation inside microchannels

Evaporation from cylindrical pore under low to moderate heat flux, fluid flow effect in pore/slots during evaporation, high heat flux, and evaporation in an inclined microchannel.

• Evaporation in porous media

Wedge or cone in porous medium, and inverted meniscus in porous media.
