Abstract By means of hot wire anemometry technique and flow visualizations, the presence of the phenomenon of the bistability around three cylinders in two triangular arrangements is investigated in an aerodynamic channel and in a water channel. Bistability occurs in flows over sets of bluff bodies forming a flip-flopping wake characterized by a biased flow switching at irregular intervals, which can represent an additional source of dynamic instabilities. Results of flow around three cylinders in triangular arrangement are presented for two configurations: one cylinder upstream and two downstream, and vice versa. The experimental data are analyzed by means of statistical, spectral and wavelet tools. The joint analysis in time and frequency domains through wavelets allows the detection of non-permanent flow structures. The results show the presence of bistable flow in the configuration with one cylinder upstream and two downstream, but no bistable effect was detected in the second configuration, where the flow shows a distinct shedding frequency.

About National Digital Library of India (NDLI)
NDLI logo

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.
