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 کاملExperimentally Validated Model of Transient Heat Transfer between a Magnetocaloric Packed Particle Bed and Stagnant Interstitial Fluid
Typical simulations of packed bed active magnetocaloric regenerators rely on correlations of Nusselt number as a function of Reynolds number. These models are well understood for large ranges of Reynolds number, but experimental data is lacking as Reynolds number approaches zero. Within a typical magnetocaloric refrigeration cycle a zero fluid velocity or dwell condition is present. When a cycl...
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...
متن کاملModels for Predicting Thermal Performance of Packed Bed Energy Storage System for Solar Air Heaters – A Review
Packed bed is generally recommended for attaching with solar air heater in order to store thermal energy of hot air. For designing such a system under the given system and operating parameters, it is required to predict performance of the system by using mathematical models. In the present paper an attempt has been made to discuss mathematical models reported in the literature for predicting th...
