This article studies the nature and causes of the dynamic loads exerted by the flow on the walls of the equipment, on an example of a curved component of the steam turbine steam supply system and examines the existing flow stabilizers used to control such loads. Based on the analysis of the shortcomings found in these devices, the article offers new designs of flow stabilizers. The newly developed devices reduce the flow area of the pipeline approximately twice less than the existing ones, so, they were supposed to have much lower hydraulic resistance. The study of the new the flow stabilizers’ efficiency was performed with the use of CFD methods and assessed in comparison with their wide used analogues. Based on the evaluation data, the designed devices provide a comparable level of decrease in dynamic loads, however, they have about five times lower hydraulic resistance. According to their design features, they are also supposed to have better mechanic strength characteristics.
