Thesis Summary:
Master’s student Sura Ammar Namuq presented hir thesis, “Energetic Performance Enhancement of the PCM-Based Photovoltaic-Thermal System: Simulation with Experimental Validation,” at the Dr. Mahdi Hantush hall in the Engineering College of the University of Baghdad on Thursday, March 14, 2024. Supervised by Asst. Prof. Dr. Jasim M. Mahdi from the Department of Energy Engineering, the thesis explores advancements in utilizing phase change materials (PCMs) to enhance the efficiency of photovoltaic-thermal (PVT) systems.
The study investigates the integration of porous aluminum fins into PCM components to maximize heat transfer surface area and improve overall PVT efficiency. A detailed 2D simulation model was developed to analyze various parameters’ effects on PCM melting dynamics, cell temperatures, and system effectiveness.
Key findings reveal that optimally configured porous fins significantly accelerate PCM melting and reduce PV cell temperatures, leading to improved thermal regulation and enhanced PVT efficiency. The study recommends the adoption of porous fins to augment PCM thermal management capabilities, citing a substantial increase in both thermal and electrical efficiency.
Objectives:
1. Conduct a comprehensive review of PCM-based solar PVT system designs.
2. Develop a mathematical model to describe PCM phase change processes.
3. Validate the model’s accuracy through comparison with experimental data.
4. Enhance PCM thermal management with porous fins.
5. Determine optimal geometric parameters for porous fins.
6. Analyze results and document findings for thesis publication.
**Recommendations:**
1. PVT systems with porous fins demonstrate higher efficiency compared to those without.
2. Porous fins accelerate PCM melting, improving PV thermal management potential.
3. Optimal arrangement of porous fins prolongs thermal regulation and enhances efficiency.
4. System inclination angle affects PCM melting time and PV thermal management.
5. Porous fins boost PVT thermal and electrical efficiency synergistically.
6. Varying system inclination angles can impact PCM melting time and cell temperature regulation.
This research offers valuable insights for advancing PCM-based PVT systems, paving the way for enhanced energy efficiency and sustainable energy solutions.
