The problem of an approximate solution to hydrodynamic problems is the consideration pressure. To exclude it from equations, transition “non-primitive variables” (vortex and velocity vector divergence) made. In this case, there are difficulties in algorithmization new equations for solving inverse hydrodynamics a lot internal iterative calculations. object study includes “non-primitive” variables. research methods based on transformation without simplifications assumptions into form containing variables demonstration possibilities equations. GAMS programming language was used solutions first time. aim paper demonstrate possibility full various conditions. results showed considering compressibility medium when hydrodynamics; identity proposed system using potential; optimizing languages problems. scientific novelty consists with use but current function.

In this paper the application of centrifugal type gas separator as a part submersible electric screw pumping unit is considered. A number bench tests have been carried out to study on viscous gas-liquid mixture. Calculation dependence delivery developed pressure single pump at angular speed rotation rotor 225 rpm for different content has made. Also, characteristic curves separators groups 5 and 5A contents viscosity mixture are obtained. methodology testing developed, which takes into account influence properties, changes in motor shaft rotation, natural separation parameters. The operating parameters group were determined experimentally, taking residual 50%, range speeds 252 – 1000 (4.2 16.7 Hz).

The coordinated operation of multiple jet devices enhances the efficiency technological processes and thrust vector control systems, enabling resolution various practical challenges. Traditional systems regulate in direction from +20° to −20° a 3D space. For first time, this study considers, general perspective, conditions under which angle can vary +180° −180° any within complete geometric sphere, including reversal. Conceptual design using computational fluid dynamics (CFD) techniques considers kinematic schemes with variable lengths flexible links. This demonstrates technical feasibility controlled energy distribution through multidirectional ejector channels, maintenance constant pressure at nozzle apparatus inlet. Potential modernization strategies for Laval incorporating rotary diffuser were examined. research outcomes are patented aimed developing digital twin system training artificial intelligence based on philosophy science technology Euler’s methodology interdisciplinary works. findings primarily applicable development efforts focused creating energy-efficient oil gas production systems. Furthermore, results be applied advanced maneuverable unmanned vehicles robotics purposes.
