Abstract

The chapter delves into the complex dynamics of hydraulic piping systems during transient events, particularly the phenomenon of water hammer caused by simultaneous valve closures. It presents a detailed analysis of the impact of these closures on pressure surges and wave interactions, using the Allievi computer code for modeling. The study focuses on a system with a 'Y' junction, examining scenarios with varying pipe lengths and diameters. The research highlights the significant pressure increases observed, which often exceed the predictions of the Joukowsky formula. The findings underscore the importance of considering wave interactions and system complexity in hydraulic system design and maintenance. The detailed discussion of simulation results and the introduction of the Over Pressure Coefficient (OPC) provide valuable insights into the behavior of hydraulic systems under extreme conditions.
