Prof. Om Prakash | Sujeet Kumar Jha "Effect of MWCNT/Water Nanofluid on Heat Transfer Enhancement in a Shell-and-coiled Tube Exchanger using CFD" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-4 | Issue-6, October 2020, pp.1004-1014, URL: https://www.ijtsrd.com/papers/ijtsrd33559.pdf

The nanoparticles have stronger characteristic of heat transfer such as high thermal conductivity, increased stability and homogeneity, along with negligible blockage in flow paths due to its limited scale and wide area. These advantages inspired the researchers to conduct heat transfer experiments. In this investigation, the heat transfer and pressure drop of the shell and coiled tube heat exchanger handling MWCNT/water nanofluids have been analyzed by the computational software ANSYS 17.0 version. The MWCNT/water nanofluids at 0.05%, 0.1%, 0.3% and 0.5% volume concentrations have been taken for this investigation. The major factors like volume concentrations of nanofluids and flow rate are considered for predicting the heat transfer rate and pressure drop. The simulation data was compared with the experimental data. It is studied that the heat transfer rate and pressure drop increase with increasing volume concentrations of MWCNT/water nanofluids. It is found that the overall heat transfer coefficient of MWCNT/water nanofluids is found to be 18%, 22%, 27% and 32% at 0.05%, 0.1%, 0.3% and 0.5% volume concentrations respectively higher than that of water at the volume flow rate range of 1–3.LPM, while the pressure drop due to MWCNT/water nanofluids may be expected more than 5%, 7%, 10% and 13 % for 0.05%, 0.1%, 0.3% and 0.5% volume concentrations respectively higher than that of water.
