Abstract. To date, numerous field and laboratory studies have been conducted worldwide on the movement of bedforms occurring in alluvial channels. Some authors have attempted to generalize this information, but so far they have not been able to achieve complet...
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...
Abstract. The article substantiates the relevance of preparing a feed mixture at the level of zootechnical demand from mixed feed with coarse and juicy feeds and feed production waste, which is important for increasing livestock productivity today, preparing i...
This article explores ways to improve the energy efficiency of electric arc steelmaking furnaces (EAFs) by enhancing the quality of electricity supplied to metallurgical enterprises. The analysis revealed that significant contributors to energy overconsumption...
The article presents the results of the author's research on the use of resource-saving technologies and technical means for gas production and transportation through pipelines, as well as their purification from foreign impurities. Considering that 75% of all...
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...
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 ...
