Coupled Thermal-Hydrological-Mechanical Behavior of Rock Mass Surrounding Cavern Thermal Energy Storage

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...

Rock Mass Response to Coupled Mechanical Thermal Loading Äspö Pillar Stability Experiment, Sweden

Short term thermal energy storage

2014 The present paper reviews the problem of short term thermal energy storage for low temperature solar heating applications. The techniques of sensible and latent heat storage are discussed, with particular emphasis on the latter. Requirements for hot water storage subsystems are provided and the importance of stratification in hot water storage tanks is described. Concerning latent heat sto...

Thermal Analysis of Thermal Energy Storage Systemwith Phase Change Material

Due to fast depletion of conventional energy sources and ever increasing demand of energy, many researchers started paying attention to renewable energy sources.Thermal Energy Storage (TES) is one of the key technologies for energy conservation and has recently been developed to a point where it can have a significant impact on modern technologies. The present work deals with the study of a sph...

A Coupled Thermal–Hydrological–Mechanical Damage Model and Its Numerical Simulations of Damage Evolution in APSE

This paper proposes a coupled thermal-hydrological-mechanical damage (THMD) model for the failure process of rock, in which coupling effects such as thermally induced rock deformation, water flow-induced thermal convection, and rock deformation-induced water flow are considered. The damage is considered to be the key factor that controls the THM coupling process and the heterogeneity of rock is...
