Solving Innovative Problems of Thrust Vector Control Based on Euler's Scientific Legacy

Abstract

This study aims to develop an interdisciplinary approach to solving innovative thrust vector control problems. The methodology involves the development of a working hypothesis about the ejection process when using a controlled nozzle to deflect the thrust vector (velocity vector) in any direction within a complete geometric sphere. When developing the working hypothesis, a multilateral analysis of individual facts and scientific and technical information is performed using tools in the "big data" area, assessing opportunities to apply the "Foresight" methodology for predicting the development of fluidics. The authors propose new mathematical models to describe the thrust vector in the distribution of the mass flow rate of the fluid medium between flow channels. Patents for inventions support the novelty of scientific results that reveal new opportunities for more active development of fluidics as applied to simple and complex jet systems with low and extremely high energy density in flows. The proposed methodology rests on a modern computer base and is a logical continuation and development of well-known Euler’s works. The computer simulation of multiflow jet devices mainly focuses on power engineering, production, and processing of hydrocarbons. Some results of this research work, including patented design developments and calculation methods, also apply to developing robotics, unmanned vehicles, and programable jet systems. The authors attribute further development of the interdisciplinary approach for solving inventive problems to the use of different AI options. Doi: 10.28991/CEJ-2023-09-11-017 Full Text: PDF

Analyzing Efficiency of Joint Operation of Gas Separator and Screw Pump on High-viscosity Gas-liquid Mixture

“…𝑄 𝑔.𝑖𝑛 𝑄 𝑔.𝑖𝑛 +𝑄 𝑙.𝑖𝑛 (22) where 𝑄 𝑔.𝑖𝑛is the volume flow rate of gas, reduced to receiving conditions (at the inlet to the gas separator), m 3 /day; 𝑄 𝑙.𝑖𝑛liquid volume flow rate, reduced to receiving conditions (at the inlet to the gas separator), m 3 /day. 2.…”

“…There are not many scientific works published in the open press, devoted to the analysis of the characteristics of downhole screw pumps on viscous gas-liquid mixtures in a wide range of gas contents. Studies of single screw pumps on viscous liquids have been reported in literature (18,19), and on low-viscosity gas-liquid mixtures also reported (20)(21)(22).…”

A New Approach to the Use of Non-Primitive Variables in the Mechanics of Continuous Media

“…This problem is so difficult to solve that successful attempts have been made to write hydromechanical equations of motion in such a way that they do not contain the explicit presence of pressure as an unknown quantity [17][18][19]. The method for removing pressure in explicit notation from the equations of hydrodynamics is the method of transitioning to "non-primitive" variables.…”

“…However, when solving hydrodynamic problems, it does not have to be determined at each iterative step of the calculation. The pressure can be determined separately from the equation written specifically for pressure determination [18,19]. The essence of the method of transition to "non-primitive" variables is as follows: each term of the equation of motion of a continuous medium is a vector, and accordingly, the "vortex" operation can be applied to each term of the equation of motion [18][19][20].…”

“…Of course, pressure will still be involved in the organization of motion, but it will be implicit. Its magnitude can, if necessary, be calculated using a separate equation [19,20]. The "primitive" variable velocity vector becomes the "non-primitive" variable velocity vector vortex.…”
