| Abstract | The durability of YZA cellular ceramic foams was investigated in the demanding environment of an instrumented porous burner. Following exposure to the combustion environment, the ceramic foam coupons suffered moderate damage. Coupons exposed to extended duration tests in the burner did not show additional damage compared to coupons exposed to short duration tests indicating that damage occurred during start-up, when temperature gradients were most severe. To compare the results of the burner tests to conventional thermal shock experiments, samples were also exposed to a water quench test. Coupons removed from the burners and coupons exposed to the water quench from high temperatures exhibited similar failure morphologies. In both cases a marked transition in failure morphology was observed as the magnitude of the peak temperatures and thermal gradients were increased. Chemical analysis combined with these thermal shock measurements show that damage sustained by the foams in the burner results from thermal shock and not from chemical degradation. |

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.
