| Abstract | In this Letter, the cooling performance of microchannel heat sinks, as well as a comparison of the heat the transfer efficiency of two nanofluids: Al2O3–water and multiwall carbon nanotube (MWCNT)–water and pure water, is investigated. At first, the same pumping power inlet boundary condition, which is a standard comparison of the performance of different fluids, is applied for a single rectangular duct, and the results are stored for the modelling of the heat sink. Following this stage, a heat sink made up of aluminium with water as working fluid is modelled. After validation of the results and optimisation of the grid, the efficiency of the three fluids is compared. It is seen that by using MWCNT–water nanofluid instead of water in a typical heat sink, the mean reduction in thermal resistance for MWCNT–water and Al2O3–water, in comparison with using water, respectively, are 18 and 1%. This shows the great advantages of using MWCNTs in heat sinks in comparison with Al2O3. |

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.
