Background: High-temperature phase change materials (PCMs) are increasingly recognized for their potential in applications such as solar energy utilization, industrial waste heat recovery, and power load regulation. These can store release significant amounts of latent heat, making them highly efficient thermal storage. Purpose: This study aims to propose analyze a novel structure enhance storage using graphite sheet combined with PCM (KNO3-NaNO3) melting point 220 K. The focus is on improving transfer efficiency understanding the parameters affecting exothermic process. Research Design: A numerical simulation approach was employed, Fluent 7.1 software method validated two examples before being applied system incorporating sheets. Study Sample: analyzed performance high-temperature thermtotal (HTTES) sheets varying thicknesses, tube spacing, temperatures, conductivities. Data Collection and/or Analysis: utilized simulations examine how different i.e. thickness sheets, spacing between tubes, conductivity PCM—affect time. Results: integration 2 mm found significantly improve efficiency. results indicated that increasing diameter influenced total logarithmic relationship observed coefficient time, suggesting diminishing returns beyond 3.5 W/(m·K). Additionally, quantity enhanced transmission overall Conclusions: provides valuable insights into HTTES systems, demonstrating findings guide design more effective supporting broader adoption technologies contributing transition toward sustainable solutions. Further research development this field essential drive advancements promote widespread implementation systems.
