A method for contact angle measurements under flow conditions

In this paper at first, a review of methods for measurements of the contact angle is presented. Following the review for contact angle measurements is developed method based on Langmuir approach. The method is aimed to be use in measurements the contact angle and rivulet's width under vertical flows as well as for the cases when rivulet does not flow down vertically along a vertical plane.
