description: Theme of the final qualification work: "Research on the effect of the number of nozzles in the stages of the LPI on the efficiency of low-flow turbines."This work is devoted to the study of the influence of the geometric parameters of microturbine plants, namely the number of nozzles, on the internal efficiency of the installation and the methodology for calculating installations of this type using mathematical models. During the study, the following tasks were solved:a. Creation of three-dimensional models of LPI stages with a different number of nozzles per stage;b. Three-dimensional computational models were developed using the modern ANSYS CFX software package;c. The calculation of the investigated options for turbine stages with the determination of the main characteristics;d. Comparison of the final results.The work was carried out on the basis of the developments of the Department of Turbine Engineering LPI, a study was also conducted of foreign analogues.The studies conducted in this work allow us to conclude that with a decrease in the number of axisymmetric nozzles, an increase in internal efficiency is observed, albeit slightly. From the point of view of production efficiency, it can also be said that a positive result was obtained in the sense that producing 12 nozzles is faster, cheaper and easier than 16.
