文摘
- •
The contact angle in capillary is generally greater than 0° and multivalued.
- •
The model of solid-liquid static contact angle considers the meniscus surface of liquid.
- •
The paper constructs incomplete wettability system contact angle model that could accurately predict the contact angle.
- •
The prediction error of the contact angle is less than 3% by using the prediction model of the paper.
- •
Experimental conclusions will play an important guiding role in research field of contact angle.
