Experimental and Numerical Simulation of Water Hammer in Water Conveyance Pipeline and Effect of Surge Tower Pipe in Controlling this Phenomenon
Water hammer is one of the unsteady flows in urban water distribution networks, which has been of great importance due to the damage caused to the pipeline and has always been of interest to researchers. In this study, the phenomenon of water hammer due to the sudden closure of the valve in the downstream end has been investigated in a laboratory and using a numerical model. In the laboratory s...
متن کاملModeling of Fluid Interaction Produced by Water Hammer
This paper compares the computational performance of two numerical methods for two models of Transient Flow. One model was defined by method of the Eulerian based expressed in a method of characteristics “MOC”, finite difference form. The other model was defined by method of Regression. Each method was encoded into an existing hydraulic simulation model. Results indicated that the accuracy of t...
متن کاملWater Hammer with Column Separation:
Column separation refers to the breaking of liquid columns in fully filled pipelines. This may occur in a water hammer event when the pressure drops to the vapor pressure at specific locations such as closed ends, high points or knees (changes in pipe slope). A vapor cavity, driven by the inertia of the parting liquid columns, will start to grow. The cavity acts as a vacuum, a low-pressure poin...
متن کاملStreet Storm Water Conveyance Capacity
The street hydraulic capacity to convey storm water is dictated by the street gutter geometry and hydraulic characteristics. With the consideration of traffic safety, the street hydraulic conveyance capacity is also subject to a reduction defined by the water velocity and flow depth in the street gutter. In this study, the street hydraulic equation is re-arranged to demonstrate that the water v...
متن کاملDynamic Fluid-structure Interaction Analysis of Water-pipe Systems
Occasionally, very strict vibrational requirements are specified for sensitive equipment used in high-tech facilities, such as radar towers and synchrotron facilities. Various external and internal vibration sources such as traffic, indoor pumps and human activities can have appreciable effect on the vibration levels in such facilities [1]. In the present study, the synchrotron research facilit...
