This paper presents the design and thermal analysis of phase change materials (PCMs) for heat storage applications in industrial processes. Various PCMs are evaluated based on their thermal conductivity, latent heat capacity, and melting points to determine their suitability for high-temperature industrial environments. Simulation results indicate that specific PCMs can significantly enhance heat storage efficiency, leading to better energy utilization. The findings provide valuable insights for selecting optimal PCMs to improve thermal management in energy-intensive industries.
