Behavior of Packed Bed Thermal Storage
A packed bed thermal storage has several desirable characteristics to be used for energy storage. The behavior of packed bed is predicted by set of differential equations. A numerical solution is developed for packed bed storage tank accounting to the secondary phenomena of thermal losses and conduction effect. The effect of heat loss to surrounding (K1), conduction effect (K2) and air capacita...
متن کاملAdiabatic Compressed Air Energy Storage with packed bed thermal energy storage
The majority of articles on Adiabatic Compressed Air Energy Storage (A-CAES) so far have focussed on the use of indirect-contact heat exchangers and a thermal fluid in which to store the compression heat. While packed beds have been suggested, a detailed analysis of A-CAESwith packed beds is lacking in the available literature. This paper presents such an analysis. We develop a numerical model ...
متن کاملSimulated Performance of Packed Bed Solar Energy Storage System having Storage Material Elements of Large Size - Part I
Packed bed or rock bed is very commonly known thermal energy storage component for solar air heaters. The major concern for design of packed bed energy storage system is to maximize the heat transfer with minimum pressure drop or pumping power. Under the given operating conditions, system parameters could affect heat transfer and pressure drop in the bed considerably. An attempt has been made t...
متن کاملSimulated Performance of Packed Bed Solar Energy Storage System having Storage Material Elements of Large Size - Part II
In the present paper an attempt has been made to report simulated performance of a packed bed solar energy storage system. Performance of the system having large size storgae material elements has been evaluated as a function of system and operating parameters. In the present part of this paper, system performance w.r.t. temperature distribution in the bed, thermal energy stored and available e...
متن کاملDynamic thermal performance analysis of a molten-salt packed-bed thermal energy storage system using PCM capsules
We investigate the dynamic thermal performance of a molten-salt packed-bed thermal energy storage (TES) system using capsules filled with high-temperature phase change material (PCM), which is identified as a promising low-cost TES system for concentrating solar power (CSP) plants. A transient twodimensional dispersion-concentric (D-C) model is modified to account for the phase change process w...
