A Review on “CFD Analysis of Heat Transfer Enhancement of Shell and Tube Heat Exchanger Creating Triangular Fins on The Tube

For evaluation of shell and tube Heat exchanger, thermal performance and pressure drop are dependent on the path of fluid flow and different orientations respectively. Increasing the complexity of fluid flow enhances heat transfer. This paper presents a review on the FEA simulations carried out on shell and tube type Heat exchanger with creating the extended surfaces on the tube wall. From the literature we found that heat transfer enhancement, is done by introduction of extended surfaces in tube side.

tube heat exchanger, Heat transfer enhancement, icem CFD, CFD fluent and ofluid, pressure drop, heat transfer is a device used to transfer heat fluid, or between two or more fluids. The fluids may be separated by a solid wall to prevent mixing or they may be in direct There are three primary classifications of heat exchangers according to their flow arrangement.
heat exchangers, the two fluids enter the exchanger at the same end, and travel in parallel to counter-flow heat exchangers the fluids enter the exchanger from opposite ends. The counter current design is the most heat exchanger, the fluids travel roughly perpendicular to one another through iciency, heat exchangers are designed to maximize the surface area of the wall between the two fluids, while minimizing resistance to fluid flow through the exchanger. The exchanger's performance can also be affected by the addition of fins or corrugations in one or both directions, which increase surface area and may channel fluid flow or induce turbulence.
Shell and tube heat exchanger: exchangers consist of series of tubes. One set of these tubes contains the fluid that must be eith cooled. The second fluid runs over the tubes that are being heated or cooled so that it can either provide the heat or absorb the heat required. A set of tubes is called the tube bundle and can be made up of several types of tubes: plain, longitudinally finned, etc. Shell and tube heat exchangers are typically used for high pressure applications (with pressures greater than 30 bar and temperatures greater than 260 because the shell and tube heat exchangers are robust due to their shape.Several thermal design features must be considered when designing the tubes in the shell and tube heat exchangers: There can be many variations on the shell and tube design. Typically, the ends of each tube are connected to plenums (sometimes called water boxes) through holes in tubesheets. The tubes may be straight or bent in the shape of a U, called U-tubes.
Literature Survey: In this work Shell and tube Heat exchanger is used to estimate the heat transfer rate. There is a lot of research going on in of them are stated below, Argonne National Laboratory of USA by Choi (1995) which showed that thermal performance of conventional liquid could be remarkably improved using nanoparticles.

CONCLUSION:
For efficiency, heat exchangers are designed to maximize the surface area of the wall between the two fluids, while minimizing resistance to fluid flow through the exchanger. The exchanger's performance will be affected by the addition of fins which increase surface area and induce turbulence.In this work the CFD simulation of shell and tube heat exchanger have been done on Ansys 14.5. Meshing of the model will be done in the icem CFD and the numerical simulations have been done in the CFD post processing Numerical validation also be done.
