This article highlights the main theoretical and practical issues of calculating general erosion processes in cohesive soil channels. The dynamics of flow saturation with particles and its dependence on flow velocity, sediment concentration, and the physical p...
The geological and physical conditions of oil deposits and the results of the analysis of the current state of development of the Akdjar field are presented. Using the characteristics of oil displacement by water, the initial recoverable oil reserves are estim...
Abstract. The article presents the content and features of the bubble method algorithm for ordering of elements of a one-dimensional array in ascending order, in which the process of elements ordering is performed by sequentially comparing every two adjacent a...
The article considers the mathematical modeling of hydrodynamic processes carried in a coal-burning furnace chamber of a gushing fluidized bed. As a result, an analytical dependence is obtained that determines the modes of motion of solid particles with differ...
The article presents the results of an experimental study of the operation processes of a solar photovoltaic power plant (SPVPP) with a total capacity of 40 kW, connected directly to the power grid, for one year. To improve the reliability of the SPVPP, the nu...
Considered one of the most widespread ancient crops in the world, soybeans are currently grown in 91 countries covering 118 million hectares. Main producers: USA 70-90 million tons, Argentina 50 million tons, China 20-40 million tons, India 6-7 million tons, R...
. Currently, one of the problems facing the Uzbekistan Railways JSC is that trains being accepted into the station from the lack of empty station tracks are waiting in front of the entrance traffic lights or at neighboring stations. As a result, the number of ...
The article provides information on a method for determining friction forces in disc tensioners of a sewing machine. This article presents calculation schemes for the implementation of plate and spring structures, graphs of the dependence of the friction force...
Under conditions of steady motion, the resulting pressure losses due to friction along the length cause a number of characteristic features of the movement of a real gas compared to the movement of incompressible liquids through pipes. At the same time, the ph...
The use of solar photovoltaic devices is becoming increasingly important in stabilizing energy security and solving environmental problems. Particular attention is paid to the scientific substantiation of factors affecting the efficiency of solar photovoltaic ...
This article presents the results of research work on a modernized solar drying plant with indirect heat pipes and natural air ventilation. The dependences of temperatures, moisture content of the steam-air mixture and on the surface of the dried grapes, the d...
