Computational Fluid Dynamics (CFD) Simulation of Mesh Jet Devices for Promising Energy-Saving Technologies

Abstract

This paper discusses the development of mesh jet devices for hybrid turbines, including developing Euler's ideas, and considers a new patented version of a mesh jet device designed to create guiding devices for turbines. The research methods are based on simulations using CFD and additive technologies. An intermediate conclusion is that a new scientific direction for the study and creation of mesh jet control systems has been formed as part of developing Euler's ideas. Calculation methods showed possible improvements in the performance of jet devices, including the use of curved tubes proposed by Euler to create turbines. This study shows that at the nozzle or mixing chamber outlet, the jet can deflect by an angle from +180° to -180° within the geometric sphere. This study also shows that the scientific groundwork prepared by Euler is not yet fully understood. The ongoing research mainly focuses on creating multi-mode jet devices designed for control systems for mesh turbomachines. Here, power consumption from an external source can be reduced to save energy. Some results of ongoing studies can also be applied in other industries (for example, when creating hybrid propulsion systems or propulsors). The scientific novelty of this work consists of improving the design methodology of jet machinery and turbomachines. Doi: 10.28991/CEJ-2022-08-12-06 Full Text: PDF

Thrust Vector Control within a Geometric Sphere, and the Use of Euler's Tips to Create Jet Technology

“…When carrying out research and development work [1][2][3][4], an interdisciplinary approach and proven methodology were used. Within the framework of this methodology, the entire set of work processes implemented in channels during the flow of gases, liquids, and other fluids is systematically considered.…”

“…As noted, previous studies [1][2][3][4], the scientific groundwork prepared by Euler is far from being fully explored. Furthermore, there are large reserves for the further progression of Euler's ideas, including within the framework of hybrid systems together with ejection processes (when the parameter 𝑄 𝑏 takes non-zero values, and the cross-sectional area of the channel at the nozzle outlet 𝑓 2 is less than the cross-sectional area of the channel at the rotor inlet 𝑓 3 ).…”

“…In the course of scientific research conducted in 2021 and 2022 [1][2][3][4], including patented technical solutions, scientific groundwork was prepared in the field of jet technology. Based on this scientific premise, in 2023 the question was raised about the possibility of forming a new scientific direction related to the use of ejection processes along with thrust vector control systems in extreme operating conditions within the complete geometric sphere (with the possibility of deflecting the thrust vector at an angle from +180° to -180°).…”

“…The most pressing problem is the reduction of energy costs in production processes, including the extraction and processing of oil and gas. Specialists from Gubkin University are studying and designing promising injection equipment and turbomachines [1][2][3][4]. In these promising systems, the flow channels have a mesh structure.…”
