description: The theme of the final qualifying work: "Optimization of circuit solutions for ventilation based on radial fans". This work is devoted to the calculation of a radial fan with further optimization of the shape of its inlet pipe in the ANSYS CFX software package. Object of the study: radial fan. Subject of the study: gas-dynamic characteristics of the fan and patterns of the flow structure obtained during the calculations. Research method: numerical simulation using the ANSYS CFX fluid dynamics software package based on the Navier-Stokes system of equations.The work was carried out using the ANSYS CFX software package. In the course of work, according to the initial data, a radial fan was selected and calculated. The radial fan has been optimized by changing two parameters of its inlet pipe. As a result, the efficiency was calculated for three variants of the radial fan: experimental, initial - calculated in the ANSYS CFX program and optimized in the ANSYS CFX program. The flow patterns and streamlines are shown in the original and optimized versions, as well as intermediate versions.
