CFD was used for the design and analysis of this heat exchanger. In the analysis water and nano fluid are taken for study. Discussion has been made on the various boundary conditions used. The resulting navier stokes equations are solved with the help of a software named as “ANSYS”. Temperature, velocity and pressure distribution are analyzed. A comparative study is made for water and nano fluid. The temperature distribution and velocity distribution are studied and analyzed for water as well as nano fluid. It is found from the results that nano fluid is more effective as compared to water KEYWORDS: STHE, CFD, Temperature Distribution, ANSYS, Velocity Distribution & Heat Received: May 03, 2019; Accepted: May 24, 2019; Published: Jun 24, 2019; Paper Id.: IJMPERDAUG201931 INTRODUCTION The important objective of a heat exchanger is the transport of heat. Almost all the processes demands a necessity of heating or cooling of fluids to obtain required thermal conditions. There is a requirement of two fluids, one that require change in energy and a second one that can provide this change. The two fluids flow inside and outside the pipe. In this arrangement the mixing of two fluids does not take place. Due to this reason this type of arrangement is useful where purity of the product is to be ensured. Another advantage of this type of arrangement is a quick transfer of large amount of heat. Kim et al. [2001] studied the hydraulic and thermal performance of multi layered fin and flat tube heat exchanger with different inclination angles. For a heat exchanger tests were conducted under different surface conditions for Reynolds number ranging between 100 – 300 at an angle of 27 degree with fin pitch and flow depth values. The inclination angle (-60<0< 60 degree) or the upstream duct presence or absence do not affect significantly the heat transfer performance in dry and wet surface conditions. But the pressure drop got increased with the inclination angle. The heat transfer coefficients and pressure drops for the wet conditions revealed the importance of the role of condensate drainage. Kakac, S. et al. [2002] studied the function and objectives of heat exchangers. Applications of heat exchanger had been studied. Classification of heat exchanger was also studied. The application of heat exchanger is also in a car radiator using an antifreeze engine cooling fluid. It was told that fishes and whales circulation system also uses heat exchanger. In this case it was studied that one of the side is having cold blood and the other is having hot blood. Also the important thing studied was that this helps in preventing heat loss while swimming in cold water. The importance of heat exchanger was also found in the tongues of some whales. Depending upon the various conditions like chemical composition, phase, fluid used and temperature large scale industries also found importance of heat exchanger. Kumar, Ravi et al. [2002] reported the transfer of heat during film condensation of R-134a and steam over a single finned tube.
