| Abstract | The simulation of positive dc corona streamer pulse characteristics at various air pressures and humidities for a rod-plane electrode system has been investigated. A flux-corrected transport (FCT) algorithm, based on a non-uniform mesh, and a successive over-relaxation (SOR) algorithm were applied to solve the continuity equations and Poisson equation in a fluid model to produce positive streamer pulse waveforms. The values of the various coefficients for humid air, considered as a gas mixture of air and water vapor and necessary for the calculations, were estimated by linear interpolation from the values for the separate ‘gases’. The simulation results were in general agreement with the experimental ones of our previous study. The positive streamer average amplitude decreased as the pressure was reduced or the humidity was raised. The phenomenon was explained by the decreasing of the average electric field and the conductivity in the discharge channel. |

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.
