| Abstract | An experimental and theoretical investigation is conducted on the effect of inlet slug length and fluid properties on slug dissipation in an enlarged impacting tee-junction (EIT). The EIT is the building block of a multiphase manifold. Prediction of the slug dissipation length in the EIT provides a guideline for the optimum diameter and length of a manifold. A multiphase flow loop is utilized to investigate slug dissipation in an EIT. The EIT inlet pipe is inclined slightly upward at 5 degrees, in which stationary slugs of different lengths are formed. The generated slugs are pushed into the EIT branches by a pre-determined gas flow rate. Over 80 experimental runs are conducted with superficial gas velocities between 3 to 9 m/s and inlet slug lengths between 40d to 90d, for both air-water and air-oil flows. The experimental data confirm that increasing the superficial gas velocity, as well as the slug body length in the inlet pipe lead to increasing the slug dissipation length in the EIT branches. Furthermore, the data demonstrate that higher slug dissipation length is obtained with water as compared to oil. A mechanistic model is developed for the prediction of slug dissipation in an EIT. A comparison between the developed mechanistic model predictions and the experimental data show a discrepancy less than 20%. |

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.
