2/2/2024 0 Comments Water hammerDynamic simulation is also applied to designing large-scale systems, such as a plant as a whole. The range of models we study has been increasing in complexity and expanding in line with the advancement of computers and tools. For simulation modeling, we use all required data such as equipment size, moment of inertia, performance characteristics of the equipment, capacity and resistance of pipes and vessels, flow characteristics of the valves and valve stroke speed, to simulate actual phenomena with superior precision. The appropriate tool is selected in accordance with the subject and contents of the study. Process dynamic simulation is essential for undertaking system operability and controllability assessments, safety measures, equipment sizing and appropriate control system designs from the standpoint of dynamic operation of the plant.

Some booster systems facilitate a pressure build up function and can be pre-programmed to minimise the risk of water hammering. To avoid this, it can be an advantage to fill the system slowly and let the pressure build up over a longer period of time. Water hammering also becomes a risk when filling empty pipe systems. The water hammer effect appears when the pipes are full, and the fluid suddenly stops its movement. A diaphragm tank can also help suppress the effect of water hammering. In applications where a quick closing of the valves is needed, special shock absorbers can be applied. On some solenoid valves, the closing time can be prolonged, thus reducing the effect of a water hammer. Non-return valves are often used to avoid the shock reaching the pumps, thereby minimising the risk of destroying the pumps. Water hammering becomes a risk when valves are quickly closed in a piping system (such as solenoid valves). In commercial building applications, noise is often a topic, and in that perspective avoiding water hammering is very important. In tall buildings, water hammering is often an issue because of the high geodetic differences which often necessitate high pressure and high velocity in the build-up phase. This can result in a pressure wave which stresses the pipes, creating noise and in some cases destroying the pipes. ![]() Since water is almost incompressible, the energy of the moving water has nowhere to go if a valve is suddenly closed. The water hammer pulse sent through the pipes is the sudden pressure build-up that occurs when water quickly changes momentum in a closed system. It often leads to pipe noise or even destruction of pipes, valves etc. The phenomenon often occurs when filling an empty pipe or quickly closing a valve. Water hammer is a destructive force that relates to the incompressibility of water.
