This paper presents a modeling approach for acid treatment of carbonate reservoirs, taking into account the geological structure of the near-wellbore zone. Using real field data from the Matonat and Western Kruk fields, parameters such as the Damkyuler number,...
In this article, the hydrodynamic characteristics of a Banki (cross - flow) turbine designed for micro - hydropower plants operating under low - head water flow conditions were investigated using digital modeling methods. The main objective of the study is to ...
This article addresses the issues of mathematical modeling of water flow velocity and pressure parameters. The theoretical basis relies on the Bernoulli and Navier – Stokes equations, while the dynamic and kinematic viscosity of water is analyzed. To determi...
Enhancing heat transfer efficiency in energy systems is a critical scientific challenge. The relatively low thermal conductivity of conventional heat transfer fluids limits the intensity of heat exchange processes. In this study, classical theoretical models w...
This paper explores methods for analyzing automatic control systems (ACS) and optimizing controller parameters using the Python programming language. A third-order dynamic model of a heat exchanger is adopted as the research object. The study presents algorith...
It is known that, despite the high accuracy of water balance forecasting, existing models such as AquaCrop, SWAP and HYDRUS do not fully take into account the relationship between water - salt balance and the effect of temperature limitations on root growth. M...
The uneven distribution of loads across phases in low-voltage power supply networks significantly affects the quality of electricity, voltage regimes, and power losses. This article presents a comparative analysis of the influence of symmetrical and asymmetric...
This article analyzes the effect of pressure (0.1 – 100 MPa) and temperature (20 – 250°C) on the properties of technological fluids (HCl, water) and reaction products ( 𝐶𝑎𝐶 𝑙 2 , 𝑀𝑔𝐶 𝑙 2 , 𝐶 𝑂 2 , 𝑁 2 ) during acid t...
