| Abstract | The radial motion of a gas bubble has been widely investigated in various studies using different theoretical models. The aim of this study is to compare, qualitatively and quantitatively, the results obtained by optical recording with those of a theoretical model. Bubble oscillations were optically recorded using an ultrafast digital camera, Brandaris. The radius-time, R(t), curves are directly computed from 128 video frames. The resting diameters of the air bubbles were 26-100 /spl mu/m. The ultrasound field was defined as an 8 cycle pulse at a frequency of 130 kHz generating an acoustic pressure of 10-150 kPa. The time and the frequency response of the bubble radial motion were compared to the Keller model. From the results, it is concluded that the Keller model can be used to accurately predict the fundamental and harmonic behavior of gas bubbles. |

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.
