Development and Verification of a Pipe Network Scale Model

The main function of a water supply and storm sewer pipe network is to properly maintain planned flow rates, pressure, depth within pipes. This can be simulated with numerical analysis model. In general, model experiments are required verify correct the accuracy models, but due nature complex facilities, scale related studies very limited. Therefore, this study aimed develop kit capable general-purpose for sewage networks, verified applicability developed through simple experiments. A set experimental parts, including manhole connections, venturi meters implementation measurement, was manufactured three-dimensional printer (Stratasys F170). angle, height difference, slope could adjusted. connection cap implement all commercial circular pipes diameter 300 mm 1,200 based on 1/50 scale. transparent acrylic used. EPANET indicated that experiment network, 13 manholes, 18 pipelines, 5 had error about 13% in total pipeline 8% meter measurement value. addition, determine change according angle pipe. Results simulations FLUENT showed similar trend change.
