| Abstract | Aiming at the problems of low efficiency, easily overload and having humps of the TS100–200 centrifugal pumps, four impellers are designed with different blade curves to improve the performances of the pumps. Non-overload design method is adopted for parameters selection of impellers. The 3-D models and the 1.61 million structure grids were generated by Pro/E and ICEM respectively. After the boundary conditions of velocity inlet, outflow in the outlet and no-slip wall were specified, and the flow model was complemented with the standard k-ε model by using the commercial software CFX 12.1. The distributions of pressure, turbulence kinetic energy and streamlines in four impellers are obtained during simulation, as well as their hydraulic performances. The wrap angle φ is a critical parameter to the blade shape. Impeller-2 with appropriate wrap angle φ shows good hydraulic characteristics and excellent inner flow patterns, and it is produced for experiments by prototyping rapidly. The test results are in accordance with the simulating results. The head of impeller-2 is 5% higher than the design parameter at most and the efficiencies are nearly 6% higher than the efficiencies of the prototype pump at the design flow rate QR. The test results also show a good non-overload performances. The results prove that it is an effective and reliable method to the optimal design of centrifugal pumps with medium-high specific speed. |

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.
