MONTOYA-PACHONGO, C et al. Effects of water inlet configuration in a service reservoir applying CFD modelling. Ing. Investig. [online]. 2016, vol.36, n.1, pp.31-40. ISSN 0120-5609.  https://doi.org/10.15446/ing.investig.v36n1.50631.

This study investigated the state of a service reservoir of a drinking water distribution network. Numerical simulation was applied to establish its flow pattern, mixing conditions, and free residual chlorine decay. The influence of the change in the water inlet configuration on these characteristics was evaluated. Four scenarios were established with different water level and flow rate as the differences between the first three scenarios. The fourth scenario was evaluated to assess the influence of the inlet configuration, momentum flow and water level on hydrodynamic conditions within the service reservoir. The distribution of four nozzles of 152.4 mm diameter was identified as a viable measure to preserve the water quality in this type of hydraulic structures.

Keywords : Computational fluid dynamics; CFD; free residual chlorine; mixing time; momentum flow; service reservoir; tracer.
