Abstract
In the present study, the heat transfer and hydraulic performance of the plain circular tube equipped with twisted tape inserts with straight helical twist with pitch of the twist as 6, 8 and 10 with DI water and DI water with higher concentration of Fe2O3nanoparticles were examined experimentally under turbulent flow regime (Re ranging from 3000 to 8,000). The concentration of the nanoparticles were varied from 1 to 2% by weight. The experimental investigation revealed that the increase in the concentration of nanoparticle with the DI water exhibited excellent heat transfer characteristics. Similarly, with increased turbulence by equipping the twisted tape insert with the circular tube improves the heat transfer characteristics and thermal performance.
