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 study presents a comprehensive three-dimensional coupled numerical model for a solar-driven desalination device incorporating a capillary-structured porous membrane (CPM). The governing equations - encompassing conjugate heat transfer, capillary-driven ma...
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 study investigates the dynamic adsorption of petroleum hydrocarbons in an organobentonite adsorption bed for the effective treatment of oil-contaminated water. Experimental investigations were carried out in a continuous-flow fixed-bed column system. The ...
Abstract. Cotton processing waste (husks and stalks) in Uzbekistan represents a significant renewable raw material for lignin production, the basis of thermo- and salt-resistant drilling fluid reagents. The choice of lignin extraction method affects its purity...
This article analyzes the theoretical foundations, technological approaches, and practical effectiveness of using energy-efficient materials in construction processes. Enhancing energy efficiency, minimizing heat loss, lowering the operational costs of buildin...
The article analyzes issues related to improving the operational reliability of centrifugal pumps widely used in the mining industry. It has been established that the primary causes of failures in pumping equipment operating in hydrotransport systems are hydro...
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 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 treatment of carbonate reservoirs. Studies sh...
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...
This article presents theoretical studies aimed at reducing soil compaction caused by the tires of four-wheel tractors used in vegetable cultivation and harvesting under the soil and climatic conditions of our republic. The paper describes the structural desig...
This article examines the issues of improving the efficiency of chemical treatment of productive formations in oil and gas wells. Due to the shortage of hydrochloric acid and the increase in its cost, the possibility of using phosphoric acid for treating produ...
This article analyzes the production technology of sulfur-based polymer concrete and its environmental efficiency. Compared to traditional cement-based concrete, the manufacturing process of sulfur polymer concrete significantly reduces carbon dioxide (CO₂) em...
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 ...
The increase in electric vehicles has made ensuring energy balance at charging stations a critical challenge. In this study, a hybrid model based on solar panels, wind turbines, the central grid, and battery storage was developed, and its efficiency was evalua...
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 near-wellbore zone of reservoirs of various types is characterized by complex physical and chemical processes that determine well productivity and the efficiency of stimulation methods. This study examines three independent directions of near-wellbore tran...
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 ...
