Condensation

From Thermal-FluidsPedia

Condensation occurs when a saturated or superheated vapor – pure or multi-component – comes into contact with an object, such as a wall or other contaminant, that has a temperature below the saturation temperature.

• Basics

• Dropwise condensation

Dropwise condensation formation theories, critical droplet radius, thermal resistances, and heat transfer coefficient.

• Filmwise condensation

Regimes, governing equations for a binary vapor mixture, stagnant pure vapor reservoir, effects of vapor motion, turbulent film condensation, other filmwise condensation configurations, cylinders and spheres, flooding or entrainment limit, and effects of noncondensable gas.

• Nongravitational condensate removal

Suction at the porous wall, forced vapor flow, centrifugal field, and capillary action.

• Film condensation in porous media

Inclined wall, and effect of surface tension.

• Forced convective condensation

Two-phase flow regimes and heat transfer predictions.
