| Abstract | High-voltage charge transport in dielectric oil under slowly time-varying voltage conditions is considered. Theoretically the transport is seen to result from the formation and movement of aggregates of trapped charges bounded in tiny cells enclosing Beltram flow fields. Such entities do not interact with the fluid and can therefore accelerate as free particles for finite time intervals. They can react both with the electrostatic field and with an electrodynamic component introduced by detrapping of electrons and subsequent diffusion and retrapping on adjacent field lines, causing rotation of the fluid and mechanical acceleration, /spl omega/ /spl times/ u. This introduces a fluid dynamic analogue of the usual electrodynamic body force, J /spl times/ B. Since vorticity is thus generated, it is manifested as an effective reduction of the fluid viscosity with the superimposed effect of eddies.< |

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.
