The study of droplet-surface interaction is of great importance in the context of ensuring the safety and reliability of space flights. In particular, controlled droplet-surface interaction helps prevent the formation of free-flying droplets and ensures the supply of fuel to the engine. To simulate the interaction of a single liquid droplet with a solid surface, multiphase hydrodynamics methods are used based on the Volume of Fluid (VOF) model to track the liquid-gas interface, as well as adaptive meshes to improve the accuracy of calculations near the free surface. The mathematical model takes into account the effects of viscosity, surface tension, wetting (contact angle) and capillary forces. Specific attention is paid to the influence of the contact angle on accuracy of results of numerical simulation and droplet spreading factor. Numerical calculations are carried out for various characteristic parameters of the problem. The results of numerical modeling are compared with physical experiment data and the available correlation dependencies for the droplet spreading factor over the obstacle.
