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).

Classification and Criteria of Evaporation.
Adiabatic walls, and heated wall.
Liquid droplet in a hot gas and liquid jet in a pure vapor.
Evaporation from cylindrical pore under low to moderate heat flux and high heat flux, and evaporation in an inclined microchannel.
Wedge or cone in porous medium, and inverted meniscus in porous media.
