Heat transfer enchancement in pipes using nanoparticles and fins with different geometries

Developing electrical applications in sectors such as energy, electricity, and automotive requires creative approaches to enhance heat transfer. By increasing the heat transfer surface, tube fins in heat exchangers are key components that enhance thermal performance. However, there are several limitations that prevent typical fin designs from achieving optimal performance. Nanoparticles provide more effective heat dissipation by improving system properties and thermal conductivity. Offering greater thermal conductivity than conventional cooling systems, the use of nanofluids enhances heat transfer in tube-fin systems. This study aims to design a finned tube with different geometries and investigate heat transfer using different amounts of fixed-sized nanofluids to achieve the most effective design. Various shapes were examined for the fin study (triangular, rectangular, and circular). Studies found that the triangular finned tube was the most suitable. Different nanostructures are added to the triangular finned structures. Consequently, the optimal nanostructure and pressure expansion are achieved. The best nanoflow was found to be Al₂O₃-TiO₂ with a concentration of 10-6%. The best geometry was found to be a triangular fin.
