| Summary: | Title screen The experimental results of the water droplet impact on the tilted metal substrates are given. To establish the effect of the texture on the spreading of droplets, parallel-directed scratches were applied using a grinding machine. To analyze the shape of water droplets after impingement, topological-based data analysis (TDA) was used. The TDA showed that the droplet could be represented as a group of trivial topological structures: spheres, discs, and hemispheres. The latter creates the prerequisites for the development of relatively simple mathematical models that describe the complex processes of liquid droplets impacting on tilted, textured substrates. Moreover, the time dependence of the droplet contact line (L) and the left and right contact angles (LCA and RCA) on a textured surface were established. It was shown that anisotropic modification of the substrate has a significant effect on the characteristics and conditions of the spreading of the coolant droplets Текстовый файл AM_Agreement |
