| Abstract | The paper reaches into a circular bend mode piezoelectric micro-droplet ejection generator, and a complete relation model from the voltage pulse applied on the piezoelectric transducer to ejection parameters of high viscosity aerospace lubricant droplet was established. Based on the Finite Element Analysis (FEM), transient response analysis of FEM modal was carried out, and the vibration equation of circular piezoelectric transducer was obtained by means of curve fitting. Multi-phase computational fluid dynamics (CFD) software was involved, and the gas liquid two-phase flow near the nozzle was established. To solve the interface movements with continuing topology changes, volume-of-fluid method (VOF) along with the piecewise linear interface construction (PLIC) techniques were implemented to describe the interfacial movements. A computational approach based on VOF method was applied to analyze the ejection process of lubricant droplet. And the effects of internal factors consist of dynamic viscosity and surface tension on the ejection parameters were investigated emphatically. |

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.
