Abstract

Abstract: Detection of the pipeline leakage and its repair at an early stage is very crucial as leaks can cause significant destruction to the surrounding infrastructures. This paper demonstrates the change in flow characteristics of a low-pressure water pipeline with the existence of a narrow circumferential crack of three different sizes. The steady state simulations have shown clear indications in the velocity and mass flux variations along the pipe and at the crack surface. These results show that the crack causes measurable differences in fluid flow properties at different inlet pressure. Predicted results were analysed to assess the effect of leakage on the pressure field and maximum mass flux. The study intends to contribute in the development of pipe crack leakage detection in various industrial and commercial purposes.
