Large eddy simulation of a round jet into a counterflow

Abstract A round jet into a counterflow under different jet-to-current velocity ratios was investigated using large eddy simulation. The results agree well with experimental measurements from laser-Doppler anemometry and laser-induced fluorescence that include velocity and mean concentrations along the centerline and radial direction. Vortex rings appear in the region near the jet exit and large-scale vortex structures still occur near the stagnation point. The flow becomes more chaotic and three-dimensional with the presence of these structures. In particular, their presence near the stagnation point results in large velocity fluctuations that enhance the mixing process and dilution. These fluctuations are described by probability density functions that deviate from Gaussian distribution. The three-dimensional streamlines indicate that the jet not only oscillates in three directions but also rotates about the jet axis and around the vortex. The second and third moments of the velocity or scalar fluctuations identify that the mixing processes are greater in the region before the stagnation point.

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.
