| Abstract | Previous approaches to improve mixing between miscible liquid streams are based on lamination; introducing chaotic advection through patterned channel walls; or through three dimensional (3D) channel networks. A new mixer for miscible liquids based on segmented gas-liquid flow is presented here. It can be operated over a very large range of liquid flow rates and is therefore compatible with nanoparticle growth. In order to explore the mixing mechanism based on segmented gas-liquid flow, a micro-resolution particle image velocimetry (Micro-PIV) is used to measure the flow field in liquid segment (plug) involving liquid species to be mixed. The velocity distributions in the plug can be obtained according to the CCD image. There are two recirculating flows in the plug, which can enhance the mixing efficiency by folding and stretching the liquids occurred deterministically in these regions. Some published results were cited as a comparison. The comparison indicated that present device has a best mixing characteristic at high Peclet number. |

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.
