| Abstract | On the basis of a quick-closing valve technology, parallel-wire conductivity probes were designed to measure water hold-up of oil–water two-phase flow in near-horizontal pipe. First, the electric-field distribution characteristics of the parallel-wire conductivity probe and its response to the change of the water layer height were calculated by using finite-element method. Then, for the oil–water stratified distribution in the near-horizontal pipe with a 5° inclined angle, 20 mm inner diameter, and 1050 mm length, a measurement model for water hold-up was established. After that, a static experiment was carried out to investigate the accuracy of water-hold-up measurement. The results show that errors occur when the set water hold-up is with high values. The measurement errors were analysed based on curved oil–water interface predicted by Young–Laplace equation model, which are significantly related to the curvature of oil–water interface. It provides an effective experimental method for the measurement of water hold-up in a near-horizontal oil–water two-phase flow pipes. On the basis of this, the dynamic experiment of oil–water two-phase flow was carried out, and the slippage of oil–water two-phase flow was preliminarily revealed. |

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.
