摘要：
Formation of a liquid film on the surface of a cylinder with microtexture was studied visually. The effect of microtexture on evolution of waves on the surface of viscous liquid falling over the outer surface of a vertical cylinder under the action of gravity depending on Reynolds number is shown. The phenomenon of microwave formation on the film surface was determined; the size of these waves is comparable with the microtexture pitch.
