| Abstract | The study of the flow around a small group of circular cylinders has attracted considerable interest in recent years due to the importance of this type of flow for a better understanding of both bluff-body fluid dynamics and fluid structure interaction. The problem of two staggered stationary cylinders has been addressed by a number of authors. Significant changes in the fluid dynamics occur when the structure is allowed to oscillate naturally or is forced to oscillate. The problem of the cross-flow on an oscillating cylinder has also been studied by several authors. Less studied is a combination of the two problems whereby one or more cylinders can be forced to oscillate. This work presents an experimental investigation of the fluid dynamics around a pair of similar circular cylinders subjected to forced harmonic motion. The present study consists in determining the frequency content in the wake of the cylinders from hot film measurements. Results have shown the ocurrence of lock-in not only at the forced frequency but also at sub and super harmonics. |

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.
