INTRODUCTION
 The temperature of the gases in a reciprocating I.C.
engines varies from 40°C to 2500°C during the cycle.
 If the engine is not cooled, then the cylinder and piston
temperatures may exceed to 1500°C.
 At such high temperature, the metals will loose their
properties and expansion of piston will be considerable
and seize the liner.
 The lubrication of the engine will be badly affected if the
engine cylinder temperature exceed 80°C because the
lubricating oil will start evaporating and piston and
cylinder will be badly damaged.
 Therefor, it is essential to maintain the temperature of
engine parts below some limit by cooling.

NEEDS OF COOLING SYSTEM
 The high temperature reduces the strength of piston and piston rings
and uneven expansion of cylinder and piston may cause the seizure of
the piston.
 The high temperature may cause the decomposition of the lubricating
oil and lubrication between the cylinder wall and piston may
breakdown resulting in a scuffing of the piston.
 If the temperature around the valve exceeds 250°C, the overheating
of the valve because the scuff of the valve guides due to the
lubrication breakdown.
 The tendency of the detonation increases with an increase in the
temperature of the cylinder body.
 The pre-ignition of the charge is possible in spark ignition engine if
the ignition parts initially are at high temperature.

TYPES OF COOLING SYSTEM
Air cooling system
Liquid cooling system
 Waterless cooling system
 Water cooling system
• Thermo-syphon cooling system (Natural
cooling system)
• Forced circulating cooling system
• Cooling system using thermostatic valve
• Evaporative cooling systemEnhancement of cooling effect of an automobile system using Nano fluid-(CuO) in radiator 5
AIR COOLING SYSTEM
 In this system air is used as a
cooling medium and it is used
for small capacity engine. The
heat transfer co-efficient of air
is very low so that it can only
used in low capacity engines.
By attaching fins to the outside
the engine, the surface contact
area of the engine is increase
so that heat transfer rate is
increased. The use of fins
increases the heat transfer
surface by 5 to 10 times of its
original value.

WATER COOLING SYSTEM
 In water cooling system,
water is the heat transfer
medium. The heat carrying
capacity of the water is
higher compare to the air. In
high capacity engine or in
multi-cylinder engine water
cooling system is used. For
increasing the cooling effect
in various condition,
additives have been added
in the water, i.e. antifreeze
solution, corrosion inhibitors
(Sodium Benzoate), antifoam
additives, dyes etc.

COOLING WITH THE HELP
OF NANO-FLUID
Copper Oxide (CuO)
Enhancement of cooling effect of an automobile system using Nano fluid-(CuO) in radiator 10
INTRODUCTION
 Nano fluid is a fluid containing nanometer sized particles,
called nanoparticles.
 These fluids are engineered colloidal suspensions of
nanoparticles in a base fluid.
 The nanoparticles used in Nano fluids are typically made
of metals, oxides, carbides, or carbon nanotubes.
 Common base fluids include water and ethylene glycol.
Enhancement of cooling effect of an automobile system using Nano fluid-(CuO) in radiator 11
INTRODUCTION
 Nano fluids have novel properties that make them
potentially useful in many applications in heat transfer
including microelectronics, fuel cells, pharmaceutical
processes, and hybrid-powered engines.
 They exhibit enhanced thermal conductivity and the
convective heat transfer coefficient compared to the base
fluid.
Enhancement of cooling effect of an automobile system using Nano fluid-(CuO) in radiator 12
DEVELOPMENT AND CONCEPT OF NANO FLUID
 It is well known that at room temperature, metallic solids possess an
order-of-magnitude higher thermal conductivity than fluids.
 The thermal conductivity of copper at room temperature is about 700
times greater than that of water and about 3000 times greater than
that of engine oil.
 Therefore, the thermal conductivities of fluids containing suspended
solid metallic or on-metallic (metallic oxide) particles would be
expected to be significantly higher than those of conventional heat
transfer fluids.
Enhancement of cooling effect of an automobile system using Nano fluid-(CuO) in radiator 13
DEVELOPMENT AND CONCEPT OF NANO FLUID
 The main problems of using such suspensions are the rapid
setting of particles, clogging of flow channels and
increased pressure drop in the fluid.
 In contrast, nanoparticles due to their high surface to
volume ratio can remain in suspension and thereby reduce
erosion and clogging.
Enhancement of cooling effect of an automobile system using Nano fluid-(CuO) in radiator 14
WHY USE NANOPARTICLES?
 The basic concept of dispersing solid particles in fluids to
enhance thermal conductivity can be traced back to
Maxwell in the 19th Century.
 Studies of thermal conductivity of suspensions have been
confined to mm - or mm - sized particles.
 The major challenge is the rapid settling of these particles
in fluids.
Enhancement of cooling effect of an automobile system using Nano fluid-(CuO) in radiator 15
WHY USE NANOPARTICLES?
 Nanoparticles stay suspended much longer than micro-
particles and, if below a threshold level and/or enhanced
with surfactants/stabilizers, remain in suspension almost
indefinitely.
 Furthermore, the surface area per unit volume of
nanoparticles is much larger than that of micro particles.
 These properties can be utilized to develop stable
suspensions with enhanced flow, heat-transfer, and other
characteristics.

Nano Fluid a
coolant for
air finned
heat
exchanger:
The Review
Nano fluids are
differentiated as
metallic and nonmetallic
nanoparticles according
to material type since
different nanoparticles
need their own stability
method. various
nanoparticle types with
different base fluids are
invented and they are
studied. The main aim
of this review paper is
to summarize the use of
modified coolant for
heat exchanger by using
Nano fluid along with
their properties.
From literature survey it is
observed that these fluids offer
higher thermal conductivity
compared to that of
conventional coolants like ethyl
glycol. Some of the Nano fluid
copper oxide, Iron Oxide,
Aluminum Nitride are explain
with different preparation
method. Various way of
calculating properties of the
fluid are also mentioned in this
review. Therefore, further
research investigations are
needed to comprehensively
understand the stability of Nano
fluids before evolving new
energy efficient heat transfer
fluids specific to applications

Effect on
Convective
Heat
Transfer of a
Heat Sink
Different parameters affecting
the heat transfer characteristics
were investigated so that the
influence of each parameter
can be determined. Three
volumetric fractions of
nanoparticles as = 3.5, 4, 4.5
and 5 vlo% were used to prepare
the Nano fluid for the
experiment. The Reynolds
number varied from 400 to
2000, the convective heat
transfer coefficients were
determined. The results gained
in the study showed that
dispersion of CuO nanoparticles
in water significantly increased
the overall heat transfer
coefficient while thermal
resistance of heat sink
decreased.
• CuO nanoparticles
dispersed into the water
increased heat transfer
coefficient of the heat
sink significantly. This
outperformance can be
mainly attributed to
higher thermal
conductivity of the Nano
fluids and Brownian
motion of particles.
• Amount of augmentation
in heat transfer
coefficient increased with
increasing particle
concentrations and the
amount of heat transfer
enhancement did
decrease at higher
Reynolds numbers.

Experimental
Study of Heat
Transfer in a
Radiator using
Nano fluid
This study attempts
to investigate the
heat transfer
characteristics of
an automobile
radiator using
water combination
based CuO Nano
fluids as coolants.
Thermal
performance of an
automobile radiator
operated with Nano
fluids is compared
with a radiator
using conventional
coolants.
The heat transfer rate for
CuO-water Nano fluid at
volume fraction 10% was
studied. The results indicate
that the overall heat transfer
coefficient of Nano fluid is
greater than that of water
alone and therefore the total
heat transfer area of the
radiator can be reduced.
However, the considerable
increase in associated
pumping power may impose
some limitations on the
efficient use of this type of
Nano fluid in automotive
diesel engine radiators.

  • 6. AIR COOLING SYSTEM  In this system air is used as a cooling medium and it is used for small capacity engine. The heat transfer co-efficient of air is very low so that it can only used in low capacity engines. By attaching fins to the outside the engine, the surface contact area of the engine is increase so that heat transfer rate is increased. The use of fins increases the heat transfer surface by 5 to 10 times of its original value. Enhancement of cooling effect of an automobile system using Nano fluid-(CuO) in radiator 6

  • 13. DEVELOPMENT AND CONCEPT OF NANO FLUID  It is well known that at room temperature, metallic solids possess an order-of-magnitude higher thermal conductivity than fluids.  The thermal conductivity of copper at room temperature is about 700 times greater than that of water and about 3000 times greater than that of engine oil.  Therefore, the thermal conductivities of fluids containing suspended solid metallic or on-metallic (metallic oxide) particles would be expected to be significantly higher than those of conventional heat transfer fluids.

  • 14. DEVELOPMENT AND CONCEPT OF NANO FLUID  The main problems of using such suspensions are the rapid setting of particles, clogging of flow channels and increased pressure drop in the fluid.  In contrast, nanoparticles due to their high surface to volume ratio can remain in suspension and thereby reduce erosion and clogging.

  • 15. WHY USE NANOPARTICLES?  The basic concept of dispersing solid particles in fluids to enhance thermal conductivity can be traced back to Maxwell in the 19th Century.  Studies of thermal conductivity of suspensions have been confined to mm - or mm - sized particles.  The major challenge is the rapid settling of these particles in fluids.

  • 16. WHY USE NANOPARTICLES?  Nanoparticles stay suspended much longer than micro- particles and, if below a threshold level and/or enhanced with surfactants/stabilizers, remain in suspension almost indefinitely.  Furthermore, the surface area per unit volume of nanoparticles is much larger than that of micro particles.  These properties can be utilized to develop stable suspensions with enhanced flow, heat-transfer, and other characteristics.

  • 19. Author Definition Abstract Conclusion Mostafa Jalal, Hossein Meisami and Mohammad Pouyagohar Experimental Study of CuO/Water Nano fluid Effect on Convective Heat Transfer of a Heat Sink Different parameters affecting the heat transfer characteristics were investigated so that the influence of each parameter can be determined. Three volumetric fractions of nanoparticles as = 3.5, 4, 4.5 and 5 vlo% were used to prepare the Nano fluid for the experiment. The Reynolds number varied from 400 to 2000, the convective heat transfer coefficients were determined. The results gained in the study showed that dispersion of CuO nanoparticles in water significantly increased the overall heat transfer coefficient while thermal resistance of heat sink decreased. • CuO nanoparticles dispersed into the water increased heat transfer coefficient of the heat sink significantly. This outperformance can be mainly attributed to higher thermal conductivity of the Nano fluids and Brownian motion of particles. • Amount of augmentation in heat transfer coefficient increased with increasing particle concentrations and the amount of heat transfer enhancement did decrease at higher Reynolds numbers.

  • 20. Author Definition Abstract Conclusion Parashurama M S, Dr. Dhananjaya D A, Naveena Kumar R R Experimental Study of Heat Transfer in a Radiator using Nano fluid This study attempts to investigate the heat transfer characteristics of an automobile radiator using water combination based CuO Nano fluids as coolants. Thermal performance of an automobile radiator operated with Nano fluids is compared with a radiator using conventional coolants. The heat transfer rate for CuO-water Nano fluid at volume fraction 10% was studied. The results indicate that the overall heat transfer coefficient of Nano fluid is greater than that of water alone and therefore the total heat transfer area of the radiator can be reduced. However, the considerable increase in associated pumping power may impose some limitations on the efficient use of this type of Nano fluid in automotive diesel engine radiators.
