| Abstract | Thermal spreading or constriction resistances exist whenever heat flows from one region to another in different cross sectional areas. In this study, the ideas of Isotropic half-space and Heat flux tube are numerically modeled in order to estimate the thermal spreading/constriction resistance. Furthermore, the thermal spreading resistances of the Silicon in arbitrary temperature and heat flux ranges are calculated for assessing the temperature-dependent thermal conductivity effects. Finally, different sizes of contact area in the Heat flux tube pattern are used to obtain the effect of contact size on the thermal spreading/constriction resistance. Results clearly indicate that the thermal spreading/constriction resistance is affected by the temperature-dependent conductivity of solids, shape of contact surface, size of contact and boundary conditions. |

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.
