| Abstract | Inspired by the successful applications of biological non-smoothness, the bionic non-smooth surface was integrated into the design of hydrodynamic torque converter (TC) to conduct the research on the drag reduction and efficiency improvement, the concaves model on non-smooth surface were established according to our analysis with the mechanisms underlying non-smooth unit mediated fluid drag reduction. The friction, shear and turbulent viscous in the concaves and adjacent areas on bionic non-smooth pump surface were found to decline after TC was subjected to transient numerical simulation tests using computational fluid dynamics (CFD) analysis method. The results showed that the head and efficiency of bionic pump was improved, compared with the original model, as well as the over performance of TC, the availability of the proposed design method could be thereby confirmed. As a kind of "green drag reduction" method, the bionic non-smooth surface was firstly applied to TC in this paper, the correlation reflected from non-smooth shell surface of pump can be provided for the design involving the drag reduction on surfaces of other internal components in TC. |

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.
