| چکیده | ||
| This study explores the melting behavior of phase change materials (PCMs) within a triple-tube heat exchanger (TTHX), focusing on the effects of fin geometry, heat exchanger material, and heat transfer fluid (HTF) temperature. A numerical investigation using the enthalpy-porosity technique was performed to evaluate the thermal performance of the system. Results indicate that increasing the number of fins significantly reduces the melting time by enhancing the heat transfer surface area. Among various materials that were tested, copper exhibited the highest thermal conductivity, achieving the fastest melting time and most uniform temperature distribution. Furthermore, raising the heat transfer fluid temperature from 86°C to 98°C reduced the melting time by over 60%, emphasizing the critical role of fluid temperature in the phase change process. These findings provide insights into the design and optimization of phase change material (PCM)-based thermal energy storage systems for applications in building energy management and renewable energy systems. | ||
