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 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...
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...
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 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...
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 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...
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...
Research in the field of hydrodynamic calculations of the flow of gas-liquid mixtures in pipelines has been carried out by many researchers. They theoretically and experimentally studied various hydraulic and hydrodynamic features of gas-liquid flows. However,...
The аrticle is devoted to the cаlculаtion of a hydrаulic shock аbsorber with а diаphrаgm installed at the end of а pressure pipeline. Theoreticаl solutions of hyperbolic type wave equations for а polytropic process (n = 1.20) аre proposed.To dаmpen the intensi...
