Event Details | 2nd International Conference on Energy and Power (ICEP 2018) Delivery In person Event Date 13 to end of 15 Dec 2018 Event Location Sydney, Australia Event Venue CQUniversity Sydney Campus Event Description The International Conference on Energy and Power (ICEP) aims to provide a forum for scientists, engineers, researchers and educators from around the world who are involved in energy and power research, development and innovation. The conference will enable the participants to present and discuss the latest trends and findings and to learn the state-of-the-art technologies in relevant topics and applications. The 1st ICEP, held in Melbourne in 2016, was a great success. Over 100 participants from across the globe attended the conference. Event Web Address (URL) |
Abstract | A three-dimensional computational conjugate heat and mass transfer study has been carried out using computational fluid dynamics (CFD) software package ANSYS FLUENT to investigate the effect of insert’s twist ratio on the heat transfer and fluid flow performance. Investigation was carried out for air flow at 300 Kelvin and Reynolds number ranging from 3642 to 21857 through a tube with constant wall heat flux of 8000 W/m2. Validating against Gneilski and Petukhob models, the current model has been used to investigate the effect of insert with twist ratio 3.46 and 7.6 on Nusselt number, friction factor and thermal performance factor of the tube. Results show that for twist ratio of 3.46, Nusselt numbers and friction factors are increased by 20% to 62% and 185% to 245% respectively, and thermal performance factor ranged between 0.9 and 1.2. Those were observed to be increased by 10% to 30%, 128% to 183% and ranged between 0.95 to 1.05 respectively for twist ratio of 7.6. It is concluded that twisted tapes provide better heat transfer enhancement at relatively lower Reynolds number and twist ratio. |
