| Abstract | Summary form only given. The behavior of a wall stabilized argon arc at atmospheric pressure subjected to a transverse magnetic field is investigated by solving the arc conservation equations based on local thermal equilibrium (LTE) and relevant Maxwell's equations. The Lorentz force consists of two components: one due to the interaction of the arcing current with the externally imposed magnetic field and the other with its own magnetic field. Two methods, the net emission coefficient and the partial characteristic method, are used to calculate the radiation transport. The Lorentz force produces two vortices symmetrical with respect to the tube diameter, which is parallel to the Lorentz force. The highest temperature region is moved towards the wall in the direction of the Lorentz force. Computational results are given for currents from 40A to 120A and the imposed magnetic field up to 22.5mT. The computed temperature, electric field, and pressure are compared with the experimental results of Sauter (1969). At high currents, there is a good agreement between prediction and experimental results. The agreement becomes progressively poorer when the current is reduced. This is attributed to the assumption of LTE, which is no longer valid in certain regions of the arc at low currents. |

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.
