The aim of this article is the analysis of the hydraulic transient flows in pressurized pipes using Computational Fluid Dynamics (CFD). The model uses a three-dimensional efficient mesh with a refined mesh in the viscous sublayer, corresponding to the best compromise between the maximum accuracy and the minimum computational effort. CFD results have been compared with collected data from an experimental...
Air chambers show good ability in controlling the pressure surge from a water hammer (WH) phenomenon. To simulate an air chamber and study the behavior of air inside it, a compressed air vessel (CAV) is considered in a pressurized system. The current work consists of experimental tests and one-dimensional (1D) and two-dimensional (2D) computational fluid dynamics (CFD) simulations for an air pocket...
