| Abstract | A new valveless piezoelectric pump, which integrates mixer and pump, is proposed, based on the theory of the piezoelectric pump with the Unsymmetrical Slopes Element(USE). It is designed not only two inlets and one outlet, but a Rotatable Unsymmetrical Slopes Element(RUSE). When the pump works, two fluids flow into the inlet channels, respectively. The RUSE can be rotated to adjust the flow resistances of the two inlet channels and varies their flows. It can realize the ratio control of the two flows. The fluids form a net flow due to the USE principle, while they are mixed into a homogeneous solution due to strong turbulence flow field and complex vortexes generated by RUSE in the chamber. And then the solution is exhaust out of the outlet. All of these processes realize the integration of mixing and pumping functions. Firstly, theoretical analysis on this pump is performed. Meanwhile, the flow field in the chamber is calculated and simulated. And then, the relationship between the flow of the pump and the rotating angle of the RUSE is established and analyzed. Finally, experiment on this pump is carried on. It shows that the empirical data and the theoretical data share the same tend. On condition of 20° RUSE, the maximum error between the theoretical flow and the empirical flow is 11.14%, and the maximum error between the theoretical flow ratio of the two inlets and the experimental one is 2.5%. All of these verify the theoretical analysis. |

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.
