| Abstract | Mean concentration fields of strongly advected non-buoyant discharges are characterised with a double-Gaussian assumption. Comparisons with experimental data show that the approximation provides a reasonable representation of the cross-sectional profiles. The self-similarity of these profiles enables their form to be represented by two additional parameters, one describing the relative separation of the peaks and the other the ratio of the cross-sectional spreads. Values for these additional parameters are determined from experimental data. This systematic approach to characterising the strongly advected flows provides a consistent framework for determining spreading rates and concentration ratios, such as the peak to centreline maximum and the peak to top hat. The double-Gaussian framework also provides a basis for comparisons with the CorJet and VisJet numerical models. In addition the double-Gaussian assumption is employed to interpret data obtained using the Light Attenuation technique. This is a relatively simple measuring system, which provides depth integrated concentration information. The data obtained using this technique is shown to be generally consistent with that from previous studies. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
