This document provides an overview of a project to compare the thermal properties of conventional coolants and nanofluid coolants. The main objectives are to achieve the highest possible thermal properties at the smallest concentration. Literature was reviewed on applications of nanofluids as coolants and how they can improve cooling system efficiency. Nanofluids will be prepared using a two-step method and characterized at different concentrations. The expected outcome is that nanofluids made with nanoparticles like copper, copper oxide, and CNT in organic and inorganic solutions can achieve 30-50% more efficiency than conventional fluids.

2. PROJECT OBJECTIVE
 The main objective of this project is to
achieve the highest possible thermal
properties at the smallest possible
concentration.
 Here we compare conventional and Nano
fluid coolant and find out which has better
thermal properties so that it can be used in
lathe, turbines and nuclear reactor.

3. MOTIVATION
 The motivation of these study is to develop a better understanding
of the influence of cutting parameters and cooling strategy with
acceptable tool life and cycle time.
 Ethylene glycol based Nanofluid is used in radiator as coolant in
automobile industry.
 Nanoparticle in water used as a coolant in nuclear reactor for
cooling purpose.
 In summer season when high temperature could damage electric
generator and mechanical parts of turbine using Nanofluid as
coolant it dissipate heat in the environment.

4. INTRODUCTION Nano particles are particles between 1 and 100 nanometers (nm) in size
with a surrounding interfacial layer. It cannot be seen by human naked
eye
 When a ray of light falls on Nano particle then the spectral lines are
formed.
 Continuous technological development in automotive industries has increased
the demand for high efficiency engines. There are many systems which
influence the engine performance like fuel ignition system, emission system,
cooling system, etc. one of the parameters which affects the performance of
engine is the cooling rate of radiator in engine cooling system.
 In this developing technology more the depend on the Nano particles will make
all round development of technology and to over come the energy crisis.
 Classifications
 Nanoparticles can be classified into different types according to the
size, morphology, physical and chemical properties.
 Nano particles are also classified based on Carbon, metals,
semiconductor, polymeric and ceramics

6. PREPARATION OF NANO-FLUIDS
 The preparation of the nanofluids for long term is the first task.
For this purpose,
 we would be using a two-step method in which nanoparticles or
nanotubes are first produced as a dry powder.
 The resulting nanoparticles are then dispersed into a fluid in a
second step.
 After the preparation of the nanofluids, we would check the
following characterization:
 Prepare the nanofluids of 3 different concentrations
1. Low concentration
2. Average concentration
3. High concentration

LITERATURE REVIEW
 Sadollah Ebrahimi: studied about application of nanofluid as
coolants. Today more than ever ultrahigh performance cooling
plays an important role in the development of energy-efficient heat
transfer fluids which are required in many industries and
commercial applications
 Steve Choi: studied about how to improve cooling system
efficiency. Nanofluids, nanoparticle-fluid suspensions, are new
class of heat transfer fluids engineered by dispersing nanometer
size solid particles in heat transfer fluids.
 R J Bhatt: did work on the thermal abilities of nanofluids as
coolants. Today, the demand of automobile vehicles is on peak

8. EXPECTED OUTCOME
 By mixing Nano particles such as copper, copper oxide, Multi walled
CNT with some organic and inorganic solutions( methanol, ethanol &
water), we can achieve 30-50% of more efficiency compared to
Conventional fluids.
 Smaller the nano particles less will be the melting point
