Water is supplied to most of the countries using the pipeline. The major problem in these pipelines is leakage and due to this a large amount of water is being lost. To improve the pipeline system and also to reduce the loss due to leakage a proper leak detection system should be used. A lot of research is being carried in the field of leak detection but analysis of leakage and its flow parameter using CFD (Computational Fluid Dynamics) is a new and unique technique that reduces the cost of experiments and bulky setup. In this paper, review of various research carried in the field of leak detection using experimental techniques and analysis using CFD is discussed.
