Abstract

Several cases of computer simulation for transient flow have been conducted to demonstrate the transient effects in distribution system. Each case is simulated with specified scenarios. The results of computer model show that any changes of water demand can produce large pressure oscillation. If the change of demand is sudden, it will create many undesirable consequences such as backflow, excessive high pressure, or negative pulling pressure. The computer model utilized in this study has been found to be a promising simulation tool for the solution of transient flow in distribution system. Computer models have to be used for the design of distribution system subject to transient flow. Moreover, it can be used as an operational tool to protect the distribution system from the excessively high pressure, the column separation due to excessive negative pressure, or any undesirable incidents.
