| Abstract | Multistage centrifugal compressors are widely used in the oil and gas industry for various applications. As energy demand increases, the compressor has been challenged to have both high efficiency and broad operating range in order to minimize the life-cycle operation cost. Therefore much effort has been devoted to improve performance of the centrifugal impeller through various design methods. This paper highlights experiences gained in the development of three-dimensional impeller design in an effort combining different design methodologies and experimental investigations. In the present paper, a radial impeller in a medium specific speed range was designed through the conventional direct approach as the baseline. Then, it was redesigned with a different loading profile and a challenged loading magnitude by means of the inverse design method. To assess the two design approaches, the resulting two impellers were manufactured and tested in a closed-loop compressor test rig. The experimental investigation consists of both the performance test and detailed traverse test measuring the flow field downstream of the impeller. The paper presents the comparison of impeller performance and time-averaged data of the downstream flow field between the two impellers. Analysis of the test data illustrates the critical impact of the blade loading on the overall compressor performance and stability. |

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.
