Application of Genetic Algorithm in Optimal Design of Surge Tank in Pipeline System

In this paper, Genetic Algorithm is used for optimal design of surge tank in pipeline systems under transient conditions. The Implicit Method of Characteristics is used for simulation of pipeline system. The objective of using GA is to optimize the cost of surge tank in system by minimizing its volume such that an existing pipeline can resist pressure surges induced by transient operation of the system. The method is applied to two example problems of transient flow caused by valve closure. The results clearly emphasize on applicability of optimization model for the optimal design of surge tanks in pipeline systems.
