Download Deltares Wanda a practical tool for simulating the phenomenon of water hammer in water and fluid transmission lines, developed by Deltares. Ram impact is one of the most common phenomena in fluid mechanics, also known as the blue hammer. A ram is a destructive phenomenon that occurs after a sudden stop or change of direction in the liquid transfer pipes. This phenomenon increases the pressure and creates a wave and usually occurs when one of the valves closes suddenly. This software has various applications, the most important of which are to determine the size and diameter of pipes, flow distribution, pressure percussion analysis, design and size of tank surge and shock absorber, operation control in industrial units, rate analysis Heat transfer. from Direct link
