“…A practical example shows a reduction in the overshoot time. Compared to previously proposed methods [10,23,29,[73][74][75][76][77][78][120][121][122][123][124][125][126][127][128][129][130][131][132][133][134][135][136][137][138][139], the time spent on equalizing the reservoir pressure is reduced by 15%. It is important to note not only the great theoretical significance of the research conducted, but also its real practical application.…”

The most important source of human life support is water. During the development of mineral water fields, unsustainable patterns of production and consumption have been observed, which could lead to environmental damage and the deterioration of mineral water quality and sources. In this work, a procedure for determining the modified link’s parameters, replacing the static and dynamic indicators of the hydrodynamic process, is proposed. Recording the parameters at the different filtration coefficients along the spatial coordinates allows the environmental safety of aquifers to be increased and the pressure of the reservoir to be stabilized. The presented approach allows the accuracy of the process used to control the reservoir’s pressure to be increased.

Cryogenic cavitation exhibits complexities primarily represented by the coupled interactions of thermodynamic effects, vortices, and cavities during the cavitation process. To further investigate this coupling mechanism, this study employed the DDES turbulence model and Sauer–Schnerr cavitation model to perform unsteady numerical simulations of liquid nitrogen cavitation flow around the NACA0015 Hydrofoil. Numerical validation of the model utilized a symmetrical Hord hydrofoil. The results reveal that the upstream development of the recirculation flow under inverse pressure gradients is the fundamental cause of the detachment in the primary cavitation region. At a cavitation number of 0.616, thermodynamic effects noticeably suppress the formation of cavities and alter the range of adverse pressure gradients, consequently influencing the detachment behavior in the primary cavitation region.

Forecasting the development of regions is one of the most challenging tasks of modern economics. The quality of any forecast is determined by the methodology used. Accordingly, criticism of existing forecasts is largely connected to their methodological approaches. In this paper, a multi-level approach to forecasting the development of the region is proposed, starting with the definition of the key performance indicators and ending with the assessment of various scenarios. The study was conducted on the example of the Russian Arctic, divided into three technological zones, with three scenarios of the development for each (negative, base, positive). The application of the proposed methodology allowed for modeling the development of the region until 2035. The results show that the Russian Arctic has a huge difference in the achievability of different goals, e.g., 98% of the electricity supply targets are achievable in a baseline scenario, while only 52% are achievable in a set of “navigation” targets. The proposed methodology can be useful for diving into the details of regional forecasts, such as the impact of key companies in a region or the influence of international politics.
