Abstract | Ultrasonic wave can be widely used in different steps of nonomaterial synthesizing processes. The most obvious is dispersing of materials in liquids in order to break particle agglomerates. Known types of systems which are used to this purpose, composed of a liquid tank and a high power ultrasonic generator. In this paper, an ultrasonic dispersion system has been proposed and designed with new method of particle dispersing strategy. The main advantage of the proposed is decreasing dispersion time and increasing the particles size uniformity. It assumed that the mix of particles and liquid medium is passing through a cubical pipe. Suitable number of transducers embedded on one side of the pipe with optimum distance from each other, so that the ultrasonic intensity can be focused on some cavitations zones to stimulate dispersion function gradually. Evaluating of the optimum placement of transducers is calculated and simulated using FEMLAB package (COMSOL multi-physics 3.4). The ultrasound intensity profile is obtained from the pressure field distribution. This provides a prediction across the geometry of active cavitations zones, which are crucial for the optimization of the transducers placing. The results can then be used to increase dispersion systems efficiency in a real time controlled application. Simulation results show a better performance compared to the conventional methods. |

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.
