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...
Reliable prediction of channel bed deformation is essential for the hydraulic design, rehabilitation, and operation of irrigation canals with weakly cohesive beds. However, the presence of both suspended sediment and a small proportion of cohesive material com...
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...
In tasks of identifying relationships between technological parameters of automated control objects, the capabilities of neural networks are used. One of the important problems considered in such identification tasks is the choice of the neural network archite...
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...
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 ...
This article mathematically models the stationary and unsteady behavior of fluid flow in channels with variable cross-sections. The study considers the problem of determining unsteady flow parameters based on the method of small disturbances, Gurevich – Haskin...
The article presents the results of a 3D geological model of the Sherkent oil and gas field, created using Schlumberger’s Petrel software. The Sherkent structure was prepared for exploratory drilling in 2007 based on the interpretation of 3D seismic survey dat...
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...
An accident (a breach) in a dam or reservoir dyke causes a large mass of water to be compressed and displaced through the breach, dramatically increasing the flow velocity and its dynamic impact on the dam bottom and reservoir basin. This results in the breach...
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...
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...
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...
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 ...
Ensuring the continuous and reliable operation of power transformers is a fundamental requirement for modern electrical networks. The growing complexity of power systems demands innovative methods for real-time monitoring and predictive maintenance. This resea...
The most important feature of artificial neural networks, which indicates the wide capabilities and enormous potential, is the parallel processing of information by all parts. A large number of connections between neurons allows you to significantly speed up t...
