| Abstract | A multistage turbomachinery computational fluid dynamics (CFD) system was developed and used to redesign an industrial core compressor for improved performance. Overall performance improvement goals of a 1% increase in the design point adiabatic efficiency and a 5% increase in high-speed surge margin were established for this first attempt at using this new system. Outlined in this paper are the details of how advanced multistage tools were incorporated into the existing design system. Data from the baseline and redesigned configurations are presented that illustrate the capabilities of the system. The redesign activities are reviewed, with emphasis placed on the ability of the tools to adequately predict axial stage matching. A simple and economical means to increase compressor performance was found using the new CFD system. Test data confirmed that the redesign of the target compressor was successful. Engine results demonstrated a 2% increase in design speed compressor efficiency and a 4% drop in the high speed operating line with the redesigned blading installed, thereby exceeding the original efficiency improvement goal. This increase in compressor efficiency produced a 4% increase in engine shaft horsepower with a 16% decrease in the heat rate near the design turbine inlet temperature. |

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.
