description: The purpose of this paper is to analyze the effect of the inlet shape on the efficiency of an axisymmetric apparatus by analyzing flow and velocity coefficients. The first part of the paper focuses on research methods, including the use of a static in- stallation with a set of axisymmetric ducts (ASDs), the chosen object of research. The methods of processing the experimental data obtained in the course of nozzle apparatus research are also described. The second chapter focuses on the analysis of the influence of the design features of the subsonic zone of nozzle apparatuses on their performance. The influence of inlet devices on the characteristics of nozzle apparatuses and turbines is studied, the theoretical principles of design- ing a new type of inlet devices are stated, and the studies of inlet devices with different velocities of the working medium flow are carried out. The third chapter is devoted to the methods of determining the flow coefficient of nozzle apparatuses with axisymmetric nozzles and the numerical method of determining the energy losses in nozzle apparatuses with axisymmetric nozzles. The scientific novelty of this work lies in an in-depth analysis of the influence of the shape of the inlet part of nozzle apparatuses with axisymmetric nozzles and inlet nozzles on their efficiency. This study opens new horizons for understanding and improving the efficiency of nozzle apparatuses and represents a significant contribution to the scientific understanding of the flow dynamics in such apparatuses. The practical significance of the work is that the results obtained can be directly applied in design practice to optimize the design and efficiency of nozzle apparatuses. This, in turn, con- tributes to increasing the energy efficiency and productivity in various areas of industry, where nozzle apparatuses are used, including power engineering, aviation and heat exchange processes.
