Abstract Steady state simulation of a 3D model of supercritical CO$_{2}$ based natural circulation loop with end heat exchangers has been carried out employing the commercial CFD (computational fluid dynamics) code, FLUENT. The simulation considers phenomena such as viscous dissipation in fluid, axial conduction in fluid as well as in solid wall. Study has been carried out at a constant CO$_{2}$ operating pressure of 80 bar. Results are obtained for various inlet temperatures of water in the hot heat exchanger, within the range of 323–353 K, for a fixed inlet temperature of cooling water in the cold heat exchanger (305 K). Results show that heat transfer rate increases with increase in HHX water inlet temperature whereas mass flow rate of loop fluid decreases. Due to the presence of bends and strong buoyancy effects, fluid parameters such as local velocity and temperature vary in all three dimensions which justifies the use of 3D model for this study. Results also show that even for a small temperature difference of 18 K, Reynolds number reaches a high value of the order of 10$^{5}$. Validation of simulation results against experimental results reported in the literature with respect to modified Grashof number (Gr $_{ m }$) and Reynolds number (Re) exhibit good agreement.

About National Digital Library of India (NDLI)
NDLI logo

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.
