| Abstract | The performance of air-cooled plate-fin heat sinks in impinging flow differs significantly from that of similar heat sinks in parallel flow. A numerical experiment and analytical scaling has been carried out to determine the pressure drop and thermal performance of single isothermal channels with variable-width impinging flow. The flow enters the channel normal to the heat sink base. The pressure drop and thermal performance of the flow in this configuration are particularly important for analyzing plate-fin heat sinks for which axial fans supply the flow, since the fan flow rate varies with the static pressure. The results of the numerical experiment and scaling are combined into dimensionless correlations for pressure loss coefficient and channel average Nusselt number. These correlations may then be used to predict the thermal performance of the heat sink. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
