Nowadays ensure the performance of heat exchanger is one of the toughest
roles in industries. In this work focused on improve the performance of
shell and tube heat exchangers by reducing the pressure drop as well as
raising the overall heat transfer. This work considered as a different
nanoparticles such as Aluminium oxide (Al2O3), Silicon dioxide (SiO2),
Titanium oxide (TiO2) and Zirconium dioxide (ZrO2) to form a nanofluids.
This nanofluids possesses high thermal conductivity by using of this
increase the heat transfer rate in shell and tube heat exchanger. The
selected nanofluids are compared to base fluid based on the thermophysical
properties as well as heat transfer characteristics. All the heat transfer
characteristics are improved by applying of nanofluids particularly higher
results are obtained with using of TiO2 and Al2O3 compared to SiO2 and ZrO2.
Mixing of nanoparticles increased in terms of volume percentage it will be
increases the all Heat transfer characteristics as well as performance of
the heat exchanger.
