“…For example, a problem describing gas flows when flowing around a set of cylinders [17], which can form a grid or a permeable mesh structure, can be considered. Mechanical systems with certain response speed limits to control signals and commands are usually used to control gas flows [18,19]. Currently, there is a need to create faster control systems.…”

This paper presents a scientific development aimed at improving the efficiency of turbomachines through the joint use of rotary-vane and vortex workflows. In the well-known Euler turbine, the rotor flow channels represent a set of curved pipes. The authors propose to consider in more detail the possibilities of using such rotating pipes in the implementation of an ejection (vortex) workflow. A hybrid pump was considered with the conclusion that its workflow can be described using two Euler equations. The results of computer simulation indicate that hybrid turbomachines are promising. The use of additive technology allowed the creation of micromodels of the Euler turbine with various rotor designs. Laboratory hydraulic tests showed that the liquid inlet to the rotor is possible in pulse mode. Laboratory tests of micromodels using compressed air showed that gas (or liquid) motion through curved pipes could be carried out from the rotor periphery to its center and then back, albeit through another curved pipe. The research results demonstrated that the scientific and technical potential of the Euler turbine is not yet fully unlocked, and research in this direction should continue. The study results are applicable in various industries including the energyeconomy, robotics, aviation, and water transport industries.

Wing-In-Ground (WIG) Effect Vehicle can be differentiated into manned and unmanned aerial vehicle. These aircraft are designed in aerodynamic shapes to enables them to glide at low altitude above the sea surface. Proper design of wings and stabilizer is crucial to provide effective lifting force with minimum total body weight. A study was conducted to determine the orientation and shape of the wing and stabilizer for a new WIG Effect vehicle prototype. Three-dimensional modeling and air flow analysis were carried out to analyze the lifting force generated under the provided body construction materials and total gross weight. In this study, two wing designs and wing orientations were studied since the WIG Effect vehicle is not equipped with wing aileron or wing flap. The first design is called as original design which suggested by industrial fabricator and the second design is called as modified design suggested from this study for design improvement. The modified wing exhibited the largest lifting force, which applied the Bernoulli’s Principle in the design. Modified wing at 20° angle of attack has been selected as the best orientation of wing.

This research discusses developing an Euler turbine-based hybrid mesh turbomachinery. Within the framework of mechanical engineering science, turbomachinery classification and a novel method for mesh turbomachinery design were considered. In such a turbomachine, large blades are replaced by a set of smaller blades, which are interconnected to form flow channels in a mesh structure. Previous studies (and reasoning within the framework of inductive and deductive logic) showed that the jet mesh control system allows for operation with several flows simultaneously and provides a pulsed flow regime in flow channels. This provides new opportunities for expanding the control range and reducing the thermal load on the turbomachine blades. The novel method for performance evaluation was confirmed by the calculation: the possibility of implementing pulsed cooling of blades periodically washed by a hot working gas flow (at a temperature of 1000°C) and a cold gas flow (at a temperature of 20°C) was shown. The temperature of the blade walls remained 490–525°C. New results of ongoing research are focused on creating multi-mode turbomachinery that operates in complicated conditions, e.g., in offshore gas fields. Gas energy is lost and dissipated in the throttle at the mouth of each high-pressure well. Within the framework of ongoing research, the environmentally friendly net reservoir energy of high-pressure well gas should be rationally used for operating a booster compressor station. Here, the energy consumption from an external power source can be reduced by 50%, according to preliminary estimates. Doi: 10.28991/CEJ-2022-08-11-017 Full Text: PDF
