Sažetak
Horizontal liquid film flow sheared by an external air flow field is encountered in many engineering applications. Taking into account its physical complexity and high cost of experimental investigation, numerical simulations are nowadays considered as a valuable alternative. They are becoming a useful tool for detailed understanding of complex flow characteristics and transport phenomena, especially in situations where experimental measurements are infeasible or too expensive. The focus of this paper is the implementation and validation of a mathematical model of surface tension effects within the existing numerical framework in order to achieve a more accurate description of the liquid wall film phenomena. After literature review, optimum mathematical model has been chosen and implemented in commercial computational fluid dynamics (CFD) code. Validation was carried out using a well established case of isothermal droplet spreading for which there are analytical expressions. Comparison of simulation results with non- dimensional droplet profile shows excellent agreement with analytical results and gives confidence for commercial application of implemented model.
