| Abstract | In order to investigate the underwater laser propulsion, the collapse features of a laser-induced bubble near target surface of three different sizes are studied by the experiment based on the optical beam deflection method and the numerical simulation based on VOF method. The propelling force F and the impulse IB generated by the collapse bubble are calculated. The results show that the smaller the target surface is, the smaller the maximum bubble radius is. In addition, the smaller the target surface is, the more fiercely the bubble collapses, and the larger the pressure generated by the collapse bubble is. However, the smaller the target surface is, the smaller the peak value of F is. This occurs because F is the integral of the pressure over the area, where the impact of area is greater than the pressure. Furthermore, F decreases to negative after the maximum as a result of the shock wave generated by the collapse bubble propagating along the target surface. |

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.
