1. Introduction• Whenever there is a temperature difference in the medium, there will be a transfer of energy in term of heat. • Heat can transfer from high temperature to low temperature in three modes:• Conduction (transfer heat across a solid)• Convection (transfer heat across a fluid)• Radiation (no medium need in order to transfer heat)

1.2 Motivation The understand of the performance of the heat exchanger in term of heat transfer and pressure drop becomes essential to the design engineers
The heat transfer that occurs in the heat exchanger is usually dominated by convection mode.
