Thesis Abstract
Thermal energy storage systems (TESS) can enhance the viability of solar power generating systems by providing un-interrupted power production during periods of partial cloud cover. TESS also enable power production for a few hours after dusk.
Various TESS will be investigated with special emphasis on high temperature phase change materials (PCMs) as the heat storage medium.
Modelling of the heat exchange processes to predict the performance of TESS charging and discharging for different combinations of PCMs and heat transfer fluids will be carried out and the results summarised to identify the optimal combination.
