dc.description.abstract-translatedIn this article, we show the results of a study of the structure of a turbulent flow behind a square cylinder. Namely, for the series of points that have the highest standard deviation value. During the experiment, we were changing the position of the square cylinder relative to the total flow. Experimental data were obtained using Constant Temperature Anemometry. As a result of the analysis, we obtained graphical distributions of the main parameters of the turbulent flow. They revealed that the maximum value of the Reynolds number based on the Taylor micro-scale is observed exactly at the cylinder angle of 30° and 45°. It was also found that the distribution of the energy dissipation rate, depending on the angle of rotation of the cylinder, has a certain sinusoidal character with local peak values. The results of the analysis also showed that the distribution of values of dissipation scale and dissipation time at some distance from the cylinder has the largest range of their values.en
