| Abstract | This research presents results from experimental investigations on helix-finned surface fabricated by a 3D printing technique to evaluate boiling heat transfer performance. The experiments were conducted in saturated water at atmospheric pressure. To the author’s knowledge, this is the first attempt that helical pin fins are employed in thermal management. The boiling curve of the enhanced surface was characterized by a much lower wall superheat at the same heat flux compared with plain surfaces. High-speed visualization was used to display instantaneous bubble behaviors such as the bubble departure frequency, which was obtained from analyzed images. It was observed that the helix-finned surface had higher bubble departure frequencies compared to plain surfaces and an earlier onset of nucleate boiling was noticed. It is concluded that the surface roughness and micron level cavities produced by the 3D printing technique on the helix surface are key factors to enhance boiling heat transfer. With the experience gained, dimension optimization of helical structure should be studied further to meet the needs of increased heat dissipation rate. |

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.
