Entropy generation assessment of shell and tube latent heat storage unit
Thermodynamic optimisation for latent heat thermal energy storage unit (LHSU) is carried out using the theory of minimisation of entropy generation number. The influence of key parameters like heat transfer fluid (HTF) inlet temperature, initial temperature of phase change material (PCM) and mass flow rates of HTF on entropy generation number is analysed. Analysis is carried out for two PCMs, ...

Solar energy based thermal energy storage system using phase change materials
Nowadays for solar heating applications, usage of phase change materials (PCM) to store the heat in the form of latent heat is increased, because large quantity of thermal energy is stored in small volume. The present experimental investigation on the thermal energy storage (TES) system is developed using paraffin and stearic acid as PCM. In the present system solar energy is used as heat source ...

Numerical simulation of fluid flow and heat transfer in a phase change thermal energy storage
The objective of this work is the study of an industrial process of energy storage which consists in the use of a cylindrical tank filled with encapsulated Phase Change Materials (PCM). A particularity is present in this kind of processes; it concerns the delay of the crystallisation of PCM, called supercooling phenomenon. The development of a 2D porous-medium model for cold storage with coolant ...

CSP Thermal Energy Storage vital for utilities and grid operators
The modern age of CSP can arguably be traced back to the 354MW Solar Energy Generating Systems (SEGS) in the Mojave desert, which now make up the oldest operating plant in the world, as well as one of the largest. However, recent developments in the industry will see SEGS eclipsed by 5 projects that are scheduled to come online in 2013-14, with a combined total of 1312MW. The five plants in ...

Exergy analysis of a multi–tank thermal storage system for solar heating applications
This paper presents the results of an experimental study on the stored exergy of a stratified multi–tank system when subjected to various charge and discharge strategies. Tests were performed over 8–h and 48–h test periods, for constant temperature charging, variable input power charging, constant volume hourly draws and variable volume hourly draws. For each set of test parameters, three ...
