Val Hyginus Udoka Eze1,*, John S. Tamball1, Oonyu Robert1 and Okafor O. Wisdom2

This paper highlights the significance of modeling Latent Heat Thermal Energy Storage (LHTES), temperaturebasedand enthalpy in an understanding phase transitions, emphasizing their distinct insights based on the specificapplication. LHTES systems addresses the escalating demand for efficient and environmentally friendly energymanagement across various sectors. These systems leverage Phase Change Materials (PCMs) to store and releasethermal energy during phase transitions, offering significant advantages in terms of energy storage capacity andtemperature regulation. This research provides an overview of the methodologies, applications and challengesassociated with modeling LHTES systems, which have gained prominence in diverse fields such as phase changemodeling, temperature-centric modeling, enthalpy modeling, porous medium approach, conduction-dominated andconvection-dominated phase change. This research critically reviewed heat transfer coupled with phase change insimple configurations, exploring fundamental principles and modeling of heat storage units like packed beds. Thisresearch finally highlights the crucial importance of modeling underscores its significant role in propelling thedevelopment of LHTES technology. These review paper recommended the design and development of accurate,predictive models improve LHTES systems to enhance energy efficiency and reduce ecological impacts across a widerange of applications
