Heat exchangers are used in a variety of machines for removing the heat produced by them and thus maintaining their temperature. The most commonly used type of heat exchanger is the straight tube heat exchanger and the coolant that is generally used in them is water. Although these heat exchangers are quite efficient, they can be improved upon by introducing changes in their design. Studies have shown that replacing straight tube heat exchangers with helical or spiral tube heat exchangers can aid in improving their heat transfer efficiency. Replacing water with nano-fluid as the coolant can also increase heat transfer efficiency due to their higher thermal conductivity.

In this project, the aim is to carry out the CFD analysis of a novel type of heat exchanger which has a helical or spiral tube and a nano-fluid coolant flowing through it which may help in increasing the heat transfer efficiency of the heat exchanger. Here, a model of the structure will be created using Solidworks and then, simulated and analyze the thermal conductivity and flow characteristics of the model in Ansys Fluent. After successful simulation and recording of results, an experimental analysis will be carried out to substantiate the computational results.
