| Summary: | Enhancement of heat transfer coefficient continues to
be an important research area in various fields of
engineering ranging from microelectronics to high
powered automobiles. The initial effort in the present
research study is to enhance the heat transfer coefficient
in a vehicle radiator using nanofluids with high thermal
conductivity. The world’s most abundant element ‘Carbon’
astoundingly exists in various structures and one such
form is tube commonly known as Carbon Nanotubes
(CNTs). Heat transfer enhancement in water and coolant
based systems with different concentrations of nano
particles (carbon nanotubes) have been investigated from
an engineering system perspective. One such system
considered is a “SUZUKI (800CC) - CAR RADIATOR”,
cooling circuit using different nanofluids to replace the
conventional engine coolant. In the present study, the
effect of nano-fluid heat transfer to enhance in water and
coolant based systems with multi walled carbon
nanotubes has been investigated. The improvement of
heat transfer when compared to water, coolant (water +
ethylene glycol 60:40) and water with MWCNTS and
coolant with MWCNTS has been studied. It has been observed that there is an enhancement of
heat transfer up to 30% when coolant and CNTS are
used as a cooling medium. |
