wettability

wettability (wet´əbil´ətē),

n the angle at which a droplet of liquid interfaces with a horizontal surface; the shape of the droplet varies depending on the type of liquid and surface, thereby influencing the contact angle and thus the wettability. The greater the angle past 90°, the greater the wettability.

Wettability of the vitreous and materials is calculated by measuring the contact angle.
The improved (tertiary) oil recovery technologies such as chemical, gas injection and thermal recovery operations are implemented to recover these huge amounts of trapped oil by resulting favourable alterations in fluids-solid interactions, namely spreading, adhesion and wettability.
The wettability evaluation of the wood by determination of the contact angle is difficult, since the wood surface shows a certain roughness, inherent to its anatomic structure.
