Water Hammer Simulation in Pipeline Using Numerical Models

Hydraulic shock, often known as water hammer, is a serious problem in pipeline systems that can cause major harm and operational problems. Engineers can now comprehend the characteristics of the water hammer phenomenon and create practical mitigation solutions because to the effectiveness of numerical modelling tools in simulating and analysing the phenomenon. This study uses numerical models to offer a thorough analysis of the modelling of water hammer in pipes. The introduction of the study gives a history on water hammer, including its causes, effects, and applicability to pipeline systems. It emphasises the necessity of precise and effective numerical simulations of water hammer occurrences, taking into account variables including pipe geometry, fluid characteristics, valve dynamics, and boundary conditions. A thorough description of the creation and application of a numerical model for water hammer simulation is provided. The chosen numerical technique is used to discretize the governing equations, such as the momentum and continuity equations, and incorporate the necessary boundary conditions. To determine the numerical model’s accuracy and dependability, validation against experimental data and/or analytical solutions is done.
