Abstract
- Spiral coil heat exchangers are widely used in chemical processing, refrigeration, food industries, power plants, and HVAC systems because of their compact size and enhanced heat transfer characteristics. The present study focuses on the experimental and numerical investigation of thermal performance in a spiral coil heat exchanger under varying operating conditions. The experiments were conducted by circulating hot and cold fluids through a spiral copper coil arrangement, while parameters such as inlet temperature, flow rate, pressure drop, and overall heat transfer coefficient were Numerical analysis was carried out using Computational Fluid Dynamics (CFD) techniques to predict temperature distribution and flow behavior inside the coil. The results obtained experimentally were compared with numerical simulations to validate the thermal model. It was observed that the heat transfer rate increased with an increase in flow rate and coil curvature due to enhanced turbulence and secondary flow formation. The numerical results showed good agreement with experimental data, with deviations within acceptable limits. The study concludes that spiral coil heat exchangers provide superior thermal efficiency compared to conventional straight tube exchangers and are suitable for compact thermal systems.
