Abstract
The impact of convolutedness of capillary on the capillary rise of wetting liquid in a single tortuous capillary is studied. By introducing tortuosity and fractal dimension for a tortuous capillary, analytical expression for time evolution of the height/weight of capillary rise is obtained. It is found that the accumulated weight of liquid imbibed into a single tortuous capillary is independent of the shape of a capillary in the early rising stage.Keywords
