| Abstract | Numerical simulations of a clean room were conducted by software FDS5.3 using large-eddy simulation (LES). A computational fluid dynamics (CFD) model was first verified by comparing computational results with results of reduced scale clean room fire tests. The temperature near the ceiling round the fire location with three sizes acetone liquid fire were then studied for a typical full-scale clean room. Results show that the temperature near the ceiling is varied mainly due to the heat release rate (HRR). When the fire area is 0.5 m (meter) × 0.5 m, the excess temperature, near the ceiling in a horizontal distance 4.5 m from the fire centre, is below 50 K (kelvin) during the whole process; when the fire area is 2.0 m × 0.5 m, the temperatures above the ambient (300K), near the ceiling in a horizontal distance respectively 0.5 m and 2.5 m from the fire centre, get 50 K almost at the same time. However, under air ventilation, the temperature next to ceiling decreases fast with distance from the fire, so the radius of the smoke spread along the ceiling becomes small. |

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.
