Time-reversal of water-hammer waves

Muhammad Waqar et al.

Summary: Time reversal (TR) techniques are widely used and robust to damping, allowing for applications in various fields including medical treatment, material detection, and communication. This paper investigates the applicability of TR-based methods for damped water-hammer waves and shows that while the spatial resolution is maintained, damping reduces the amplitude of the refocused wave, potentially affecting resolution in the presence of noise.

Design criteria and performance analysis of a smart portable device for leak detection in water transmission mains

B. Brunone et al.

Summary: This paper presents the criteria for optimal and market-oriented design of the Smart-Portable Pressure Wave Maker (S-PPWM) device, which is used for fault detection in pressurized transmission mains through Transient Test-Based Techniques. The design procedure focuses on minimizing volume for improved portability and easily evaluating the minimum detectable leak for a given test TM, while ensuring the safety of the test TM in terms of maximum generated overpressures and air entry prevention during transient tests.
