“…For example, Rehman [2] investigated heat transfer coefficient optimization in a shell-and-tube heat exchanger using CFD simulations. Meanwhile, Rajeshkumar et al [3] conducted a study on heat transfer analysis in fin and tube heat exchangers, demonstrating the potential for enhanced heat transmission through design modifications. Kaushik et al [4] explored convective heat transfer in corrugated channels, revealing significant improvements with specific corrugation shapes.…”

The paper presents an analysis of the heat transfer process on heating surfaces made with different materials in a fire tube water boiler supplied by natural gas. The analysis was based on analytical calculations and numerical simulations using ANSYS Fluent software. The analytical calculations were performed to investigate the flue gas composition as a product of the natural gas combustion process and to apply these results in numerical modeling of heat transfer phenomena between hot exhaust gas and water in the boiler’s heat exchanger. The obtained results show that optimization of heat exchanger design is crucial for efficient heat transfer process in every boiler, which has important implications for the energy efficiency of those systems and environmental protection due to fuel consumption reduction. This research provides valuable insights into the importance of heat exchanger design and its impact on the efficiency of water boilers.

In some engineering applications, it is very desirable that the heat exchanger is as light as possible while maintaining the heat transfer rate at an acceptable level. In this context, the possibility of reducing the weight of the heat exchanger with the star-shaped fins by cutting off the thermally least efficient part of the fin was investigated. For this purpose, the rear part of the fins was trimmed to Ø28, Ø31 and Ø34 mm. Numerical analysis was used to determine the influence of each variant on the flow characteristics in the air–water heat exchanger and on heat transfer for the range of 2300 < Re < 16,000. The best results were obtained by trimming the rear part of the fin to Ø28 mm. With a 5.53% reduction in fin weight, heat transfer can be increased by up to 8.12% compared to the star-shaped fins without trimming. The pressure drop can be reduced by up to 0.92%. The trimmed fins were also compared with perforated star-shaped fins (perforation Ø2). At approximately the same weight, the trimmed fins increase the heat transfer coefficient by up to 5.75% with a reduction in pressure drop of up to 0.76% compared to the perforated fins.
