Sensitivity Analysis of Hydraulic Parameters on Contaminant Intrusion in Transient Conditions

Hydrodynamic Features of Two-Phase Oil–Gas Flow in Pipelines

The results of the experiments on the transport process of fluid flow through a pipeline under temperature gradient conditions between the internal and external environments, and on continuous gas generation at the contact boundary of the transported media, are presented in this paper. The test results showed that unde...

On solving the problems of maximizing the development of oil reserves in the drainage zone of wells and reservoirs

A new experimental finding regarding the violation of Darcy's law during the flow of liquids in a microcrack with an opening less than its critical value h<hcr, i.e., the manifestation of the "microcrack-fluid" effect is observed, which is the reason for the violation of Darcy's law. It has been revealed that when liqu...

Volume of fluid-based CFD study of triggering and eruption in urban storm sewers

Geyser eruption in urban drainage is a high-velocity discharge of an air–water mixture driven by intense air–water interactions. It is sudden, destructive and strongly non-linear, and is often associated with air entrapment, surcharge flows during intense rainfall and transient hydraulic processes, posing risks to drai...

Study on the Factors Affecting the Stability of Drainage Foam in Coastal Power Plants and the Aeration Pattern of the Overflow Weir

Coastal power plants draw seawater from the open ocean through their cooling-water circulation systems. The cooling water falls over an overflow weir inside the siphon well, entraining large quantities of air, and generates a foam pollution plume upon discharge to the sea. By combining physical model experiments with n...

Water hammer study in rigid and viscoelastic pipelines with sensitivity analysis of overpressure and damping

Hidden Risks to Sustainable Operation of Water Systems: Suffosion Process Triggered by Pipe Leakage

Failures and leakages in water distribution pipelines affect the sustainable operation of water supply systems. While water losses caused by leaks are widely recognized, their impact on soil stability and internal erosion processes remains insufficiently investigated. This study examines water flow velocity distributio...
