TL;DR: In this article, a comparative study of the pipe flow of water-in-crude oil emulsions was performed using a small-scale flow loop and a SARA analysis was made on all crudes.

TL;DR: In this article, two charging experiments of a solar heat storage are presented, where the heat storage is coupled with a self-circulating solar parabolic trough filled with thermal oil (Duratherm 630).

TL;DR: In this paper, a heat storage consisting of only rocks and that with rocks and phase change material (PCM) has been designed and built and the results showed that the introduction of PCM cylinders in a bed of rocks for heat storage not only increase the energy content of the storage but also increases the vertical thermal conductivity.

TL;DR: In this article, experimental results regarding the charging of two different heat storages with a small-scale low-cost solar parabolic trough are described, and the main objective is to compare the efficiency of the charging for these storsages and conclude.

TL;DR: In this paper, the average rate of heat loss from the TES unit to the ambient is found to increase with increasing average bed temperatures, and the system tries to establish thermal equilibrium irrespective of the bed height.

TL;DR: In this article, the authors summarize the motivations behind utilizing the smoothed particle hydrodynamics (SPH) method in an industrial context, as well as deriving general conclusions regarding its assets and limitations and stressing the remaining challenges in order to make it an hand-on computational tool.

TL;DR: In this paper, the thermal characteristics of a finned heat pipe-assisted latent heat thermal energy storage system are investigated numerically using a transient two-dimensional finite volume based model employing enthalpy-porosity technique.

TL;DR: The discrete element method has been in development since 1970s and has recently found practical application in simulations of granular assemblies to investigate natural phenomena as well as a design tool for technology as discussed by the authors.

TL;DR: In this article, the authors summarize the key aspects of packed-bed thermal energy storage systems and compare the performance of different types of thermal storage systems, including two-tank molten salt technology and thermal stratification.
