| Abstract | The present work focuses on a new method based on chemi-ionization to measure the flame flickering frequency. The flame flickering behavior was determined using the ion generation rate of the flame, characterized by measuring the saturation current with ion probe. A systematic comparative study was conducted by applying ion probe and other methods, such as flame detector, digital camera in the premixed flame. The flame flickering behavior was described using the frequency spectrum obtained by time series data of different technologies. Results indicate that the chemi-ionization method show excellent ability in measuring flame flickering frequency. Meanwhile, ion signals presented some detailed difference compared to the common technologies. Furthermore, by setting ion probe in different positions of the flame, frequency distribution can be measured and applied to evaluate the degree of non-uniformity and instability of combustion field. |

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.
