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...
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...
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...
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 paper presents the development of an automatic fruit sorting system based on color characteristics using an Arduino microcontroller and a TCS230 color sensor. The proposed system is designed to detect external color features of fruits in real time, proces...
This article examines the problem of determining hydraulically stable cross-sections for open channels. The potential of using the shear stress method to ensure the scour resistance of the channel bed and banks is analyzed. The shear stress method is based on ...
The article is devoted to the analytical calculation of the main parameters and dimensions of a pneumatic-hydraulic damper of hydraulic shock with pressure reduction, installed at the beginning of a pressure pipeline to reduce the emergency consequences of the...
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...
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...
Under the influence of the vortex zone formed at the confluence of two channels, sediments intensively settle. Taking these sediments into account, the hydraulic and geometric parameters of the flow are determined. The analytical solution shows that at the con...
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...
This paper presents an integrated analysis of geological field data and the current development status of the Shortak gas-condensate field. Through interpretation of hydrodynamic well test results, reservoir filtration parameters were determined, including the...
The work is devoted to the study of water hammer during the start-up of pumps in automated stations with low inertia of moving masses and taking into account energy losses during filling of the pressure pipeline. The article presents an analysis of works devot...
This article focuses on developing an intelligent system for the safe utilization of Collector-Drainage Water (CDW) to mitigate the negative impact of the Qosh-Tepa canal construction on the water supply of the Kashkadarya region. Considering that 73% of the r...
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...
