Abstract

Partially filled pipe flows are commonly observed in urban hydraulics, sewers and road crossings. The occurrence of a compression wave in the confined space may result from flash flooding, transient operation or accidental blockage, inducing explosive conditions. In this study, the propagation of a compression wave was studied in a relatively large laboratory flume of semi-circular cross-section. The unsteady flow properties were recorded to understand how the circular cross-sectional shape impacted the surging water propagation. Both free-surface and velocity data indicated a marked impact of the compression wave passage, with large instantaneous fluctuations comparable to and sometimes larger than observations of compression waves in rectangular channels.
