Abstract: There has been a lack of data on the amplitude, statistical, spectral and spatial properties of turbulence-induced boundary pressure pulsations in partially filled pipes. This information is important for the design of new wall mounted sensors that can potentially measure flow characteristics such as velocity, depth, turbulence spectra and energy. It is also useful to validate and refine hydraulic models to predict the complex near wall flow patterns and turbulence characteristics in partially filled pipes. Applications relate to monitoring of flows in sewers and drainage pipes to predict the onset of blockages, changes in the wall roughness and general ability of the pipe to carry the designed flow. In particularly, this work informs the design of a novel fibre-optic sensor that enables distributed measurements of the above flow characteristics.
