An Effect of Twisted Tape with Nanofluid on the Performance of Double Pipe Heat Exchanger: A Comprehensive Review
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2019, Vol 9, Issue 1
Abstract
The phenomenon of heat transfer is employed in numerous applications such as refrigeration, air-conditioning, food processing, etc. Heat exchangers are used for efficient heat transfer and therefore, the performance of a heat exchanger is important. Cutting edge, innovative and cost-effective techniques are required to achieve efficient heat transfer. Twisted tape (TT) inserts which is a type of passive heat transfer enhancement technique are widely researched. This article delivers an assessment on diverse types of TT in double pipe heat exchangers with different nanofluids. The influence of tape inserts with nano fluids on thermal performance factor (η), Nusselt Number (Nu), friction factor (f) and rate of heat transfer are comprehensively discussed. Application of twisted tape inserts were demonstrated to be more useful in laminar flows w. r. t. turbulent flows. On the contrary, when solid nanoparticles were employed with a high value of φ, heat transfer rate was better in turbulent flows than in laminar flows.
