Analysis of capillary rise profile around a cylinder

Gu, Y., Li, D. and Cheng, P., A novel contact angle measurement technique by analysis of capillary rise profile around a cylinder (ACRPAC), Colloid Surf., A, 122, 135-149 (1997). 

In principle, the capillary depression caused by a fiber floating on a liquid surface can be used to calculate the contact angle 7], In practice, however, the relatively small depth of immersion can make it difficult to obtain sufficient accuracy. Recently, a technique utilizing image analysis has been developed to analyze the capillary rise profile around fibers or cylinders 79],...
