| Abstract | An effective method of reducing the temperature gradient in data centers (or “hot” and “cold” spots) is to minimize the maximum temperature at the rack exit plane. For a given rack’s heat load, one way to achieve this is to vary the chassis flow rate in such a way that the rack exit temperature gradient is small. In this paper, a simple algorithm based on the energy equation is developed to set the chassis flow rate such that the exit rack temperature is uniform. When compared to a constant chassis flow rate algorithm, the proposed method is demonstrated through CFD simulations to achieve significant reduction in maximum chassis inlet temperature for the same CRAH flow rate. |

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.
