Experimental investigation and COMSOL modeling for different geometrical configurations of extended surfaces
The current work presents and analyzes an experimental and three‐dimensional COMSOL simulation to address and quantify the influence of different geometric cross‐sectional shapes and types of materials (ie, brass and stainless steel) on the thermal performance of extended surfaces. Three cross‐sectional shapes (ie, circular, square, and hexagonal) were examined under various base temperatures (ie, 40°C, 50°C, 60°C, and 70°C). Additionally, two types of fin materials, brass and stainless steel, were investigated to address the impact of thermal conductivity on the temperature distribution, local heat transfer coefficient, heat dissipation rate, efficiency, and effectiveness of extended surfaces. The experimental results showed a significant increase in the heat transfer coefficient and heat dissipation rates for hexagonal brass fins over other shapes and stainless steel fins. The simulation results were validated with the experimental temperature distributions for different geometries and materials under differing operating conditions (ie, different base temperatures, with and without an insulated fin tip). The validation and evaluation of the current COMSOL simulation indicated that the simulated results had high accuracy, with less than a 6% deviation, compared with the experimental data. The current validated COMSOL model can serve as a useful tool to facilitate the design and optimization of fins under various design and operating parameters.
