| Abstract | Complex multibody and multiphase flow problems represent a significant challenge to describe computationally and to study experimentally. In this paper we describe two main physical processes, which are studied analytically and which have a wide bearing on bubbly flows. The first is the general phenomena of vorticity annihilation which occurs when in the presence of straining motion generated by neighbouring bodies or through wakes intermingling with their neighbours. The second is blocking due to the flow having to go around these bubbles, which is studied using inviscid flow theory. By applying a new methodology, we provide a clear physical argument for drift-flux correlations typically assumed in multiphase models. Finally, we show how the two processes, vorticitiy annihilation and blocking, can be combined within one theoretical model and the consequences for modeling multibody and multiphase flows. |

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.
