Computational Fluid Dynamics (cfd) Applications In Urban Drainage

CFD modelling tools enable engineers to visualise 3D flow patterns within complex structures and to represent the movement of sediments and/or dissolved materials within the flows. This approach has provided insights into, for example, sediment deposition within combined sewage storage chambers, gross solids separation in combined sewer overflows and the passage of intermittently-discharged solutes through pipes and manholes. There are a number of ways in which this work might be further developed, including the exploration of links between residence time distributions and energy losses or the development of robust time-dependent modelling methodologies. In all cases use will be made of either new or existing field or laboratory data sets to validate the CFD work.
