| Abstract | In this study, heat transfer during spray cooling was studied experimentally using water and ZnO nanofluid. Various experiments were performed using a spray nozzle impinging fluid normal to the flat end of a copper heated surface (copper cylinder 20 mm diameter). The heat flux and surface temperature have been calculated by measuring temperature gradients along the target length under steady state conditions. In this experimental study, water flow rate was varied from 15 to 25 ml/min. In the same test conditions to compare water results with nanofluids, ZnO nanofluid was sprayed at a flow rate of 20 ml/min. It can be observed that a surface temperature 74.1 °C was obtained with maximum heat flux of 102.40 W/cm$^{2}$ under the test condition for heater power 140 W and a water flow rate 25 ml/min. The use of ZnO nanofluid as a coolant is observed to increase the heat flux by about 20.2 % and decrease surface temperature of the test specimen by about 15 % at 180 W heat input and flow rate of 20 ml/min. The uncertainty in heat flux is observed to vary from 8.63 to 10.93 %. |

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.
