CFD Analysis, Of Double Pipe Parallel Flow Heat Exchanger

Heat exchanger is a device that exchange heat between two fluids of different temperature that can have solid barrier or directly mix the two fluids. The heat exchange process happens by one of the three principles such as conduction, convention, and radiation. Here radiation does not play a major role. Heat ex-changer used in many industries to transfer heat between hot and cold fluid. Here in this project, we will design and analyze counter flow of fluid in double pipe heat exchanger, basically in this project we are trying to find the best performance of double pipe heat exchanger in terms of the heat transfer rate by varying some of its parameter such as flow rate of the fluid in the heat exchange and varying the diameter of the pipe and length of the pipe. In this particular design we have used the inside pipe made of aluminum, the outside or annular pipe made of aluminum, the hot fluid and the cold fluid we have taken is water. We are using ANSYS fluid fluent analysis software for both designing the double pipe heat exchanger and to analyze the counter flow performance of the double pipe heat exchanger.
