500 ## - GENERAL NOTE
General note An energy storage system is necessary for intermittent renewable energy to capture the power when it is available and provide it to fulfill demand during the hours of unavailability. When integrating a lot of renewable power into the grid, energy storage will be essential for managing unpredictability and filling up the generation shortfall over a few hours or days. Energy storage alternatives come in a broad variety of forms, and new ones are constantly being developed as this technology becomes a crucial part of the global energy systems of the future. Because it has the potential to significantly lower energy prices and carbon emissions by a huge amount, packed-bed thermal energy storage (TES) is seen as a particularly attractive method for applications like concentrated solar power plants and to support the smart grid. Hence, packed bed TES is chosen for the study to enhance its thermal performance and make it more feasible to utilize.<br/><br/>The current study investigates both the single-phase and two-phase (Schumann model) through packed-bed using the unsteady thermal equilibrium model of porous media. The packed-bed TES system consists of a cylindrical tank filled with spherical-shaped particles as the sensible storage media. The Ergun Equation is used to compute the permeability and the inertial loss coefficient, which are used to represent the flow of heat transfer fluid through the porous medium. Numerical simulations are performed to analyze the charging and discharging behavior of the packed bed model and comparison among two-phase and single-phase models. Different rocks and their charging characteristics were studied and found thermal conductivity and specific heat capacity of energy storage materials are very crucial. Additionally, simulation results are found to be strongly correlated with the experimental data provided in the literature, confirming the accuracy of the model.<br/><br/>Among the important parameters of packed bed TES, void fraction is being taken as the focus of study in this thesis. Numerical calculations are made to analyze the effect of the variable void fraction on axial and radial temperature distribution to see the system’s thermal behavior. In the present study, for variable void fraction, Martin’s correlation and Cohen & Metzner’s correlation are taken
