An Investigation on Concurrent and Countercurrent Heat Transfer Performance in a Double Pipe Helical Coil Heat Exchanger Using CFD

Traditional heat exchangers present a significant space constraint in industrial settings. This research investigates the potential of double-tube helical coils as a compact and efficient alternative. Helical coils offer a larger heat transfer area due to their twisted design, making them ideal for applications in food processing, power generation, and beyond. Computational Fluid Dynamics (CFD) software is employed to analyse fluid flow within the inner and outer tubes. Copper, known for its excellent heat conductivity, is chosen as the material for both tubes. Water, a readily available coolant, will flow through the innertube. By leveraging the capabilities of ANSYS Fluent, the total heat transfer emanating from the exchanger walls will be comprehensively analysed. This research aims to optimize the performance of double-tube helical coils. And compare the results obtained in both software and an experimental setup of the same. By investigating different flow arrangements, we seek to unlock greater efficiency in industrial heat transfer, paving the way for a more sustainable future.
