| Abstract | A vertical hot rod of 12 mm diameter at 800 ± 10 °C initial temperature has been quenched by sub-cooled round water jet. The water jet of 2.5 and 3.5 mm diameter, at jet Reynolds number of 5000–24,000, impinges normal to the test section of SS-316. An infrared camera is used to determine the wetting front velocity on the hot test surface. The investigations are made up to 40 mm downstream locations in both upper and down sides of the stagnation point. It has been observed that during transient cooling, the wetting front velocity increases with the rise in jet Reynolds number and jet diameter. However, rewetting velocity reduces drastically for the extreme downstream locations away from the stagnation point. The reduction in the wetting front progression for the upper side downstream locations is higher as compared to corresponding bottom side locations. The correlation proposed for the dimensionless rewetting velocity predicts the experimental data of upper and bottom side downstream locations in the error band of +30 to −20 %. |

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.
