Abstract | A surrogate-based optimization framework is proposed to exploit a reduced order model (ROM) as surrogate evaluator in aerodynamic design based on computational fluid dynamics (CFD) methods. The model is based on the Proper Orthogonal Decomposition (POD) of an ensemble of CFD solutions. Full POD and zonal POD models performances are analysed with respect to their suitability to find the global optimum in an evolutionary optimization frame. Indeed, reduced order models are used as fitness evaluator to improve the aerodynamic performances of a two-dimensional airfoil. Finally, the performances of various surrogate-based shape optimization (SBSO) methods are compared to the efficiency of data-fit assisted optimization and to the accuracy of a plain optimization, where, instead, each aerodynamic evaluation is performed with the high-fidelity model. |

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.
