Abstract: A heat exchanger is a device that allows heat from one fluid pass to another fluid without the fluids having to mix together or come into direct contact which is used in power generation, refrigeration and chemical process industries. For many years shell and tube heat exchangers employ forced convection to reduce the hot fluid temperature by increasing the cold fluid temperature. In this paper to use ANSYS software and experimental computations are to examine drop in temperatures by using camphor-water as a hot fluid and water as a cold fluid with varying inlet conditions like temperature and velocity. For that cross flow heat exchanger model was reinforced and analyzed. The outcomes from the experimental were compared with CFD values. While expected that the heat exchanger by using camphor-water gives more heat transfer rate than water.

Keywords: heat exchanger, forced convection, and ANSYS.
