摘要: Abstract The capillary meniscus interaction between a floating submillimeter particle and vertical wall is experimentally studied. It proven that the interplay of image force from one side gravity buoyancy forces other can lead to appearance stable equilibrium position at finite distance wall. dependence separation on size, three-phase contact angle, parameters investigated compared with theory developed in first part this study. agreement experimental results theoretical predictions very good. A simple method for determination angle millimeter- submillimeter-size particles, attached fluid interface, described.
