Abstract

This paper highlights the significance of modeling Latent Heat Thermal Energy Storage (LHTES), temperaturebased
and enthalpy in an understanding phase transitions, emphasizing their distinct insights based on the specific
application. LHTES systems addresses the escalating demand for efficient and environmentally friendly energy
management across various sectors. These systems leverage Phase Change Materials (PCMs) to store and release
thermal energy during phase transitions, offering significant advantages in terms of energy storage capacity and
temperature regulation. This research provides an overview of the methodologies, applications and challenges
associated with modeling LHTES systems, which have gained prominence in diverse fields such as phase change
modeling, temperature-centric modeling, enthalpy modeling, porous medium approach, conduction-dominated and
convection-dominated phase change. This research critically reviewed heat transfer coupled with phase change in
simple configurations, exploring fundamental principles and modeling of heat storage units like packed beds. This
research finally highlights the crucial importance of modeling underscores its significant role in propelling the
development 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 wide
range of applications
