| Abstract | When combined with a bi-porous or a vertical liquid artery structure, thin porous layers of high thermal conductivity materials can provide high critical heat flux while maintaining low thermal resistance. They are therefore are very promising for applications in advanced heat pipes and vapor chambers. The present study characterizes the liquid supply and heat transfer performance of monolayers of sintered Cu powders. Three sets of monolayer samples are prepared by sintering Cu powders with different diameters (29, 59, 71 um). The measured heat transfer performance is relatively insensitive to the powder diameter in the low flux regime. At relatively high heat fluxes (> 20 W/cm2) monolayers with the two large diameter powders show similar liquid supply and heat transfer performance while the sample with the smallest powder size shows significantly degraded heat transfer performance due to local dryouts. |

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.
