| Abstract | The Discrete Channel Method (DCM) is presented as a new approach to model the transient multidimensional behavior of honeycomb-type catalytic converters. DCM combines a detailed modeling of effects taking place inside individual channels with the description of thermal effects occurring in the entire converter. The model is compared to experimental data measured under adiabatic conditions and to solutions generated by the finite difference method. DCM is applied to simulate the light-off behavior for different exhaust gas compositions under adiabatic and non-adiabatic conditions. The results show the influence of changing gas compositions and of radial heat losses on the performance of catalytic converters and aftertreatment systems. Hence, DCM is an effective and computationally fast method tailored for the integration in the engine analysis tool BOOST but also for stand-alone catalyst simulation. |

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.
