| Leak detection in pipe using transient flow and genetic algorithm
Young-joon KIM
The Journal of Mechanical Science and Technology, vol. 22, no. 10, pp.1930-1936, 2008
Abstract : An inverse transient method with genetic algorithm (GA) was applied to leak detection in pipeline. Transient flow
caused by valve operation was calculated using the characteristics method. The location and discharge of leak were
determined so that the difference of the calculated pressure may be minimized from the reference pressure calculated
under a given leak condition. Calculations were done for the leak at one and two locations in pipeline. Furthermore, the
effect of noise in pressure data was discussed, and the leak locations and leak discharges can be predicted precisely
even in the case of noisy data.
