Abstract The paper represents the numerical investigation of heat transfer characteristics in a pipe provided with twisted tape inserts is analyzed. The heat transfer was analyzed in a swirling flow conditions using CFD simulation. A commercial CFD package was used for analyze twisted tape for circular tube fitted with triangular cut twisted tape and circular hole cut twisted tape inserts. The twisted tape system allows a significant increase of convective heat transfer coefficient by introducing the swirl flow motion. The swirl flow motion provides greater heat transfer rate extracted from the solid surface of the tube. The depth of cuts for triangular cut 5 mm and depth of hole cut 5 mm twisted tapes were used for simulation generation. In this paper CFD analysis was used for enhancement of heat transfer rate of fluid of laminar flow. The experimental investigation were conducted in double pipe heat exchanger and these value of plain twisted tape, triangular twisted tape and circular hole cit twisted tape were taken for used simulation analysis. The performance of heat transfer rate was enhanced 1.1–1.3 times compared that the plain twisted tape and circular cut twisted tape. The data obtained from the simulation correlations for triangular cut twisted tape and circular hole cut twisted tape; and these data were correlated with plain twisted tape.
This paper summary of heat transfer characteristics and nano fluids mechanics by using single phase convection techniques. Gas having less thermal conductivity compare than the liquids having high thermal conductivity. The heat transfer enhancement improved by using nano fluids Al2O3 compared with base water. The heat transfer enhancement was analysed with plain tube and twisted tape inserts with nano fluids. The experimental investigation was analysed and reading was taken to improve the heat transfer and friction flow characteristics. The Reynolds number varies from different ranges with plain water and Nano fluids. The experimental record of nano fluid heat transfer value was increased with 2.89 percentage compare with the experimental record of plain water. The nano fluids has more concentration than the plain water.

The experimental investigation of friction factor and heat transfer characteristics of double pipe heat exchanger using aluminum oxide water based nanofluid. In this present study the heat transfer from hot water to cold water of the double pipe heat exchanger for a plain tube was experimentally investigated. This investigation also to find the heat transfer coefficient, Nusselt number, and Reynolds number. The experimental value of plain tube with water and Al2O3 was obtained from the experimental work and these two statistical data were compared with the results. The results shows that the heat transfer rate enhancement of induced with the nanofluids water based flow has give more heat transfer compared to the plain water. The Reynolds numbers were varied in the range of 5000 to 18000. The data obtained from the experimental value were compared with CFD simulation analysis. The performance of heat transfer characteristics of aluminum oxide nanofluid was enhanced compared with smooth plain water used. The experimental value of the heat transfer and friction factor characteristics was well bonding with simulation value of CFD analysis.
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.

In this article Aluminium oxide and Titanium oxide was used to get better performance heat exchanging device. A different mass flow rate of fluids used to conduct the experiment and gathered various surface temperature for analyses the heat flow augmentation. A heat flow rate Nano fluids 10 to 12% was enhanced compare with the plain base water. A heat flow with liquid flow Aluminum oxide was enhanced with +8% compare with the plain base water. A heat transfer characteristics titanium oxide were augment with raise of Re and 12% was augmented compare with the plain water. However heat flow and liquid flow heat exchanging device was increasing with volume of Nano fluids increased and leading to friction facto

Numerical investigation of heat transfer analysis was taken with different flow rates using CFD simulation. A commercial CFD package of fluid simulation in solid works was used to analyses the heat transfer and friction factor characteristics. In this present study the double pipe heat exchanger for a plain tube and twisted tape with the triangular cut copper material inserts, the heat transfer from hot water to cold water by was experimentally investigated.

In a circular tube fitted with triangular cut twisted tape inserts with twist ratio Y = 5.4 and 1.2 cm cut depths of triangular cut was used for flow analyses. A plain twisted tape caused a swirling motion and triangular cut used for the heat transfer augments. In addition that, a triangular cut twisted tape inserts increases the surface contact area of the flow motion. The performance of heat transfer characteristics, Reynolds number and Nusselt number were analyzed using flow analysis. The data obtained from the simulation analysis and these data were correlated with plain twisted tape inserts. The performance of heat transfer characteristics of triangular cut twisted tape was enhanced compared with smooth plain twisted tape.Numerical investigation of heat transfer analysis was taken with different flow rates using CFD simulation.
