| Abstract | The immersed boundary method is an effective way to handle complex geometries and moving geometries within a flow field. In this paper, two-dimensional numerical simulations of fishlike swimming are conducted based on the immersed boundary method. In the process of calculation, the velocity and pressure coupling is solved using a second-order pressure correction method and the Lagrangian force density is calculated using Physical Virtual Model. In order to verify validity and feasibility of the algorithm, flow around a circular cylinder and moving cylinder in stationary flow are simulated, and then the results are compared with other researches. After that, the modeling and simulation of fish-like swimming are conducted. At each time step, the shape and position of the fish is updated and the Lagrangian force density is calculated. The shape and position of the fish are calculated based on the motion equation and the forces acting on the boundary. Furthermore, the impacts on performance of motion frequency, wavelength and amplitude are studied. |

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.
