ABSTRACT
Detection and localization of small leaks in pipelines were early
developed using a nonlinear adaptive state observer and a special correlation
technique, based on pressure and flow measurements at the pipeline inlet and
outlet. Simulations and experiments show the results for a gas and a liquid
pipeline. This paper x-ray pipeline leak Identification using a transient-based
method on hydraulic transients of a brake system with oil at two different
temperatures, Leak effects at different frequency response were Simulated,
measured and leak detection experiment with MATLAB code were also highlighted.
The result obtained show that in certain
circumstances the brake response is slow due to the temperature and suggests an
appropriate pipe diameter to overcome this problem of low flow rate, the
transfer function obtained using the proposed method were able to measure the
presence of a leak on the pipe system. Simulations, measurements and leak experiments have shown that the early detection and localization of small
leaks in liquid and gas pipelines can be considerably improved using theoretically approximated model as
the required computational effort is
relatively small, as compare to microcomputers which can be used for leak
detection including monitoring of the inner pipeline state.
Keywords: Pipeline modelling; leak detection; transient-based method; pipeline system, leak- localization and partial differential equations
