Research on the Prediction of Static Contact Angle in Circular Capillary Tubes

Abstract:

New discovery was found by the capillary experiments with circular glass tubes and partial-wetting liquids that the partial liquid volume under moon surface could be expressed by equivalent height function H(r). Contact angle models suggested in this work, evaluated by Eq. 5, was eventually given by the concept of equivalent height, and so-determined models presented a much higher accuracy on prediction of contact angle compared to Jurin formula.
