Опис
In modern conditions, the importance of energy conservation, the use of energy-efficient technologies, and the reduction of fossil fuel resources have become key issues. One possible solution is to develop turbine units based on vortex and jet expansion turbomachines. However, studies in their performance using the computational fluid dynamics (CFD) approach need to be considered more thoroughly, i.e., using the appropriate boundary conditions. Therefore, due to the significant resource costs associated with physical modeling, researching CFD analysis for this type of turbomachine becomes more urgent. The article examines the peculiarities of numerical modeling, particularly the choice of boundary type in the calculation domain. The originality of this study lies in determining the impact of boundary conditions on gas flow within the flow parts and the parameters of channel expansion jet-reactive turbines, as conducted for the first time using the ANSYS CFX software package. The results presented for five different combinations of outlet boundary conditions will be helpful for further optimizing the geometry of jet expansion turbomachines and rationally designing turbogenerators based on them.
