The wetting and spreading of distilled water droplets on abrasion-treated aluminum alloy AlMg 6 surfaces were studied. Using the shadow method, the dependences of the dynamic contact angle and hysteresis on the arithmetic mean of the profile deviation were obtained. Based on the analysis of the height and hybrid 3D roughness parameters, a relationship between the texture and spreading of the droplet is established.

Abstract. The paper presents the experimental results on the mass evaporation rate from the moving liquid layer surface streamlined by the gas flow for different layer thicknesses. The maximum value of the mass evaporation rate was observed for a 5 mm liquid layer. Further increase in the thickness of the liquid layer causes a decrease in the mass evaporation rate. The assumption about the change in the balance of forces was made. A self-organized structure of the square-shaped spatial cells is found to form in the moving liquid layer streamlined by the gas flow. This structure has the most visible form at the maximum possible velocity of the air.

Abstract. Dynamic spreading over superhydrophobic and copper surfaces was studied experimentally under the condition of contact line movement with speed greater than 1 mm/sec. Three modes of spreading of distilled water drop over copper surfaces with sufficient typical roughness (0.591, 5.190 and 6.210 µм) were detected. The first one is drop formation when the contact line speed and dynamic contact angle increase sharply. The second mode is spreading of a drop, which is characterized by a monotonic decrease in the contact line speed and dynamic contact angle. The third one is a formation of an equilibrium contact angle at a constant wetted area (the contact line speed tends to zero, and spreading of a drop occurs as long as the driving force is greater than zero). Some features in spreading were detected on superhydrophobic surface with parameter roughness of 0.751µm compared to other substrates. During drop formation after sharp increase in the contact line speed and dynamic contact angle, there is a mode which is accompanied by a decrease in the contact line speed and monotonic increase in the advancing dynamic contact angle.
