Review on Thermal Conductivity of Nanofluids

The experimental work on heat transfer augmentation using a new kind of insert called twisted tape with continuous cut edges is carried out. The work includes the determination of friction factor and Nusselt number for new twisted tape insert having different twist ratios of 3 & 5. The experimental data obtained from plain tube and conventional twisted tape were verified with the standard correlations to ensure the validation of experimental results. The results of new twisted tape of different twist ratios have been compared with the values for the plain tube and tube with conventional twisted tape. In addition, the effects of the new twisted tape insert on the thermal performance factor are also investigated. The results obtained lead to the conclusion that higher heat transfer rates can be achieved using twisted tape inserts with continuous cut edges at the expense of a reasonable pressure drop.

The use of new kind of insert, namely twisted tape, having continuous cut edges in a horizontal circular tube with CuO-water nanofluid flowing in turbulent conditions was experimentally investigated for heat transfer enhancement and pressure drop penalty. The new twisted tape having rectangular cut made continuously on both the edges throughout the length is used with twist ratio 3 & 5, depth ratio (d/W) 0.025, and width ratio (w/W) 0.05. The experimental setup was validated by comparing the results obtained for water flowing in plain tube and tube with conventional twisted tape with the standard correlations. The CuO-water nanofluid in 0.5% volume concentration with 50 nm average nanoparticle size was used in investigations. The results of new twisted tape have been compared with the values for the plain tube and tube with conventional twisted tape for water and nanofluid both. In addition, the effects of the new twisted tape insert on the thermal performance factor are also investigated. It was concluded from the results that augmented rate of heat transfer can be accomplished with the use of twisted insert with continuous cut edges at the outlay of rational frictional penalty resulting in higher thermal performance factor.
