Abstract—Today, film cooling is widely used in axial turbines of aircraft gas turbine engines. Typically, a turbine blade has a large number of holes, and finding their optimal configuration and location is a difficult task, where it is necessary to search for the optimal combination of a huge number of factors depending on many conditions. For this reason, the experimental study of film cooling is difficult. Here modern methods of numerical simulation come to the aid of the researcher. In this paper, a study is carried out aimed at finding the optimal settings for numerical models of the working process in film-cooled turbines using conjugated 3D models of the working process, which take into account the flow in the blade and internal channels, as well as the thermal state of the blades. The stationary nozzle blades of the first stage of a high-temperature turbine, for which there are experimental data, was taken as the object of study. As a result of the research, optimal settings of numerical models were found, which allow simulating the workflow in cooled film-cooled turbines accurately and at a reduced cost. The use of these recommendations will make it possible to obtain results close to the real ones while reducing the required time and computational costs.
