Abstract Mixing is a key parameter in bioreactors studies as it can intensify mass and heat transfer and can affect biological reactions. In the present work, mixing times are investigated in a 42 L vessel with water and various polyethylene glycol and carboxymethyl cellulose solutions. To improve the physical description of dispersion induced by bubbles, the first step of our study was to characterize dispersion of tracers inside bubbly flows at various gas volume fractions for different liquid viscosities. A colorimetric technique is used in order to record mixing times corresponding to 95 or 80% of homogeneity. Bubble size is also measured at the same time by image processing. It clearly appears that the liquid viscosity impacts the mixing time value, the bubble size and the tracer propagation.

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.
