Abstract. An analysis was conducted on the global increase in demand for electrical energy and the prospects for electricity generation, particularly in the field of hydropower. The use of micro-hydropower plants (micro-HPPs) and the factors affecting the effi...
This paper analyzes the flow behavior of gas – liquid mixtures in pipelines and reviews modern approaches to hydraulic calculations of two-phase flows. The main hydrodynamic and thermodynamic factors affecting the transportation of gas, oil, condensate, and wa...
This article investigates the hydrological indicators of the Kamashi Reservoir and their impact on the meliorative condition of lands within its zone of influence. During the study, the reservoir water level, water storage volume, groundwater depth, and the so...
This paper presents an improved numerical method for calculating water hammer in pressurized pipelines under conditions of flow discontinuity and volumetric cavitation. The physical nature of the water hammer phenomenon is analyzed, and the main factors affect...
In this article, the channel deformation processes in the Amu – Bukhara Machine Canal and the main factors causing them were identified through field investigations and hydraulic modeling. The research results showed that during the period from January to June...
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...
The article presents the results of studying the conditions for well gushing in oil and gas condensate fields under development systems with priority oil extraction and gas cap gas conservation, as well as the joint operation of the oil and gas condensate part...
Using the central part of the Chardzhou stage as an example, the results of zoning the territory by the ratio of structural plans of carbonate and terrigenous deposits are presented, with the identification of 9 types of zones in the paper. Based on the analys...
Sustainable regional economic growth is a complex multi-factor process that requires an in-depth analysis of the causal relationships among economic indicators. This study evaluates the impact of meso-level indicators such as investment flows, industrial outpu...
This article analyzes the main external and internal factors affecting measurement processes in GPS navigation systems. Particular attention is paid to the sources of uncertainty that influence the accuracy and reliability of positioning results. The effects o...
The development of the multimodal transport system in Uzbekistan in recent years has been linked to the growth of freight volumes, the strengthening of intermodal connectivity, and the increasing demand for logistics services. Between 2020 and 2024, the total ...
This study focuses on the analysis of the control system for the roasting process of sulfide-containing products. The physico-chemical characteristics of the process are examined, including temperature regulation, oxygen concentration, and gas flow stability. ...
The article examines the problem of surface-wave propagation on a current featuring large-scale turbulence in flowing reservoirs. In the course of the research, a scientific analysis was carried out of the main factors influencing the processes of alongshore c...
Trombe walls integrated with photovoltaic (PV) modules were evaluated as sustainable systems enhancing the energy efficiency of buildings. The analysis was conducted on two models — with DC fans and without — under dusty and dust-free conditions. On dust-free ...
In our country, electricity is supplied primarily via overhead power lines (OPL). Due to their length, these networks experience significant voltage drops. Meanwhile, residential electricity consumption is rapidly increasing. This, in turn, requires the ongoin...
The article examines the properties of the dependence of the efficiency of solar cells in the climatic conditions of the city of Karshi on the concentration of impurities in monocrystalline silicon, which was used in their manufacture and under the influence o...
The operation of BelAZ mining dump trucks in environments with high air dust concentration has a significant impact on the technical condition and service life of internal combustion engines (ICE). This study analyzes the interactions of dust particles with co...
The article analyzes the issues of changing the hydrodynamic parameters during the stoppage of axial pumps, which is one of their unstable operating modes. The stages of the pump stoppage process with high hydrodynamic loads and changes in water flow, pressure...
The limited nature of land resources and the prevention of energy shortages as a global problem require the effective use of renewable energy sources. The drying efficiency of the main environmental factors - solar radiation, outdoor air temperature and humidi...
The results of evaluating the oil displacement coefficient by water, based on actual field development data from oil reservoirs in the Bukhara - Khiva region, which is represented by clastic rocks, are presented. A wide range of variations in the achieved valu...
