Inducing Transient Waves Interferences for Imitating Pressure Signature in Water Distribution Systems

摘要

This study adopts the concept of over-pressurizing pipelines to manage blockages and other disturbances in pipelines and expands it to a better, more advanced tool. The suggested approach introduces pressure transients into the system and manipulates it to better control the head pressure at a given point along the pipe. Through controlling pressure changes and patterns, we can imitate given pressure signatures, thus dramatically increasing the pressure oscillation and offering different assault patterns to eliminate disturbances along the pipe. Moreover, that is done while averting extreme devastating pressures that can damage the system's components and introduce high pressure for a limited period of time. The suggested approach is simulated by the Lagrangian-based wave characteristic method transient analysis model and demonstrated in a case study for different pressure signatures.
