Special Issue Information

Dear Colleagues,

The thermal energy storage systems (TES) offer very high energy savings in many of our day-to-day applications and could be a strong component of enhancing the use of renewable/clean energy based devices. Due to high environmental impact, this technology has received wide attention in recent past and dedicated research efforts have led to the development of novel materials, as well as innovative applications in very many fields, ranging from buildings to textile, healthcare to agriculture, space to automobiles, and so on. A systematic approach to update recent advancements made in the field of energy materials for thermal energy storage systems is an important aspect of current energy research and developmental work.

The proposed Special Issue will cover an up–to–date coverage of fundamentals as well as recent advancements in energy efficient thermal energy storage materials, their characterization and technological applications. Research articles based on the status updates on fundamentals as well as substantial innovations, research and development work related to various aspects of energy materials related to thermal energy systems; along with critical insight into future directions will be of high interest. Topics of interest for publication include, but are not limited to:

  • Thermal energy storage using phase change materials
  • Thermal energy storage using thermochemical method

For the numerical simulation of a heat storage based on phase change materials (PCMs) an enhanced model is presented, considering the physical effects of convection flow in the liquid phase as well as the volume change during phase change. A modified heat capacity is used to realize the phase change. The phase change material is initially defined as a liquid with temperature-dependent material properties. A volume force is added to the Navier-Stokes equations to allow a circulating flow field in the liquid phase and prevent flow motion in the solid phase. The volume change is implemented with the Arbitrary Lagrangian-Eulerian method. A laboratory phase change experiment was performed using the PCM RT42 with a melting temperature of 42 °C. The laboratory experiment was calculated numerically using the enhanced model to evaluate the numerical model and to investigate the influence of the simulation parameters on the thermal behavior of the PCM. The thermal conductivity is determined as the main influencing parameter. A good agreement of the simulated melting front throughout a major part of the laboratory experiment has been shown. COMSOL Multiphysics provides a default model for phase change, which neglects convection flow and volume change. Compared to the default model, the enhanced model achieves more accurate results but requires more computational cost for complex latent heat storage systems. Using the default model without convection can be reasonable, considering that the heat storage design is either over-dimensioned or a suitable correction factor must be applied. Full article
