| Abstract | Sewer sediment deposition represents a crucial aspect of the maintenance of wastewater systems and has negative effects on the system itself as well as the environment. Therefore, it is important to design combined sewers, as sewage collection systems with high deposition risk, with adequate self-cleansing velocity to avoid the deposition. Despite the large number of investigations, the lack of knowledge about the particle behaviour in sewers remains a major problem in the field of sewer management. In the present work, the transport of sediments in partially filled channels is investigated experimentally and the results are compared to 3D-simulations performed with a coupled Computational Fluid Dynamics (CFD) model and Discrete Element Method (DEM). This research aims to investigate the self-cleansing design concept for uniform non-cohesive sediments based on moving of existing sediments on the sewer bed. The CFD part of the simulation is carried out in the commercial CFD software ANSYS Fluent, which is two-way coupled to the commercial DEM software EDEM through its User Defined Function. EDEM enhances the particle handling capability by resolving particle contacts, modelling bonded particles and non-spherical particles. The multiphase model Volume of Fluid (VOF) is used to capture the water and air interaction and the Discrete Phase Model (DPM) is applied to track the injected EDEM-particles. This paper also examines the applicability and limitations of this coupling method in simulation of sewer systems. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
