The document discusses CFD analysis of heat transfer rate through a heat exchanger with and without fins using hybrid nanofluid. It begins with an introduction and then discusses heat exchangers, their applications, importance and common failures. It outlines the objective of analyzing heat exchanger performance enhancement by considering fins design and using hybrid nanofluid as coolant. The methodology involves using ANSYS 18.2 software for the CFD analysis. Future work could involve experimental validation and analyzing performance for different heat exchanger geometries. Key references on the topics of heat transfer enhancement techniques, nanofluids, radiator analysis and CFD applications are also provided.

3. HEAT EXACHANGER?
• Heat exchangers used to transfer thermal energy from one medium to
another for the purpose of cooling and heating.
• They are widely used in space heating, refrigeration system, air
conditioning system, power plants, chemical plants, petrochemical
plants, petroleum refineries, natural gas processing, and sewage
treatment.
• The classic example of a heat exchanger is found in an internal
combustion engine in which oil using as engine coolant flows through
radiator coils and air flows past the coils, which cools the coolant and
heats the incoming air

4. • Another example is the heat sink, which is a passive heat exchanger that
transfers the heat generated by an electronic or a mechanical device to a
fluid medium, often air or a liquid coolant.
• Importance of heat exachanger is to removed heat from engine and
release to atmosphare to improve engine peformance
• Fins design and Hybried nano fluid are used to improve heat exchanger
performance efficincy in this thesis

b) Excessive pressure drop
c) Failure of material,leading to leaks of fluid
