Heat transfer characteristics of double pipe heat exchanger with plain twisted tape insert using titanium oxide

Abstract

In an effort to improve efficiency of heat exchanging device by means of induced tape inserts using titanium oxide Nanofluids is provided. The experimental study evaluated the fluid flow and heat transfer features of the turbulent water-based Nanofluids with a concentration of 0.6 per cent. Titanium oxide of nanoparticles with a diameter of 25 nm was used in this job. The information showed that the nano-fluid heat flow coefficient was slightly greater with base water a comparable mass flow and comparable temperature. A heat flow coefficient nano fluid rises by means of augment flow rate and amount of Reynolds rises with an rise in the heat transfer coefficient. The experiment performed heat double pipe Data were produced with distinct mass flow rates for both water and nano liquids. The amount of Reynolds ranges from 110000 to 135460. The increase in heat transfer was boosted with an increase in the amount of Reynolds. The heat transfer rate was increased by 12 per cent of nano-liquids compared to simple water.
