| Abstract | The pattern of gas-liquid two-phase flow has always been a stress topic since it plays an important role on flow and heat transfer performance. Therefore, the study of flow pattern is always an important subject of two-phase flow. This paper focus on an experiment that obtains pressure signals of gas-liquid two phase flow, which are used for constructing a complex network of gas-liquid two-phase differential pressure fluctuation, recording undulate flow pressure information to compute the dynamics statistics. The compute results reveal that occurrence probability of the degree numbers of top 15 nodes is extremely higher than other ones; therefore they are the key factors of flow characteristic. Otherwise, the network possesses a high clustering coefficient, small average path length and big node degree that reflected it has long-range correlation and shot-range correlation. Also, these dynamics statistics manifested the large network with many small groups. This paper verifies a typical feature of gas-liquid two-phase flow that it brings fluctuant differential pressure from a totally new perspective, providing a reliable reference of the internal laws of different flow pattern and trend. We also achieve good identification of flow pattern in gas-liquid two-phase flow based on complex network theory. |

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.
