Abstract
A small-scale 3 x 3 pipe network was simulated to evaluate the validity of complete-mixing and incomplete-mixing models for water distribution systems under different flow rates and boundary conditions. CFD simulations showed that accurate predictions of spatially variable tracer concentrations throughout the network could be attained when compared to experimental data. In contrast, an EPANET model that assumed complete mixing within the junctions yielded uniform concentrations throughout the network, which was significantly different than the spatially variable concentrations observed in the experimental network. The EPANET model was also modified to include mixing correlations derived from previous single-joint experiments. The results from the modified model correctly reflected the incomplete mixing at the pipe junctions and matched the trend in the experimental data. Additional CFD simulations showed that networks comprised of T-junctions separated by at least several pipe diameters could be adequately modeled with complete-mixing models.
