| Abstract | A presence of a strong external magnetic field can affect a flow distribution of a liquid-metal (LM) coolant in a fusion blanket, due to magnetohydrodynamic (MHD) effects. LM blankets have some manifolds, where the coolant flow from a single supply channel is distributed to multiple parallel channels. Since these manifolds have complex geometries, an interaction between induced axial electric currents and the magnetic field reorganizes the flow to be three-dimensional. A flow imbalance in such a complicated manifold affects heat removal performances, which is closely related to the blanket feasibility and safety. This study was performed to experimentally and numerically investigate a LM distribution in MHD flows in an electrically insulating manifold with changing the intensity and orientation of the magnetic field transverse to the flows. The flow passage employed in this study is a U-turn manifold consisting of an upward rectangular duct, a U-turn branching area, and two downward ducts with insulating walls. The gallium-indium-tin eutectic alloy (GaInSn) was employed as a working fluid. The present study shows that, as the magnetic field is applied more perpendicularly with respect to the U-turn, much amount of the fluid flows in the inner downward channel than that in the outer one. |

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.
