TL;DR: In this article, the authors presented the application of method of characteristics for numerically predicting the heat charging and discharging process in a packed bed thermocline storage tank, which proved to be very efficient, accurate, required minimal computations; and proved versatile in simulating various operational conditions for which analytical methods cannot always provide solutions.

TL;DR: In this paper, a series of well-configured general charts bearing curves of energy storage effectiveness against four dimensionless parameters grouped up from the storage tank dimensions, properties of the fluid and filler material, and operational conditions (such as mass flow rate of fluid and energy charge and discharge periods).

TL;DR: In this paper, a series of generalized charts bearing curves for energy storage effectiveness against four dimensionless parameters grouped up from many of the thermal storage system properties including dimensions, fluid and thermal storage material properties, as well as the operational conditions including mass flow rate of the fluid, and the ratio of energy charge and discharge time periods.

TL;DR: In this paper, the arterio-venous anastomoses (AVA) play a major role in the blood circulation in the peripheral body parts, and a segmental bioheat model of Salloum et al. is improved to accurately predict skin blood flow rate in the hands and fingers, and the local and overall human thermal responses in transient environments.

TL;DR: In this article, an experimental study of the energy charge and discharge processes in a packed bed thermocline thermal storage tank for application in concentrated solar power plants is presented, and a mathematical analysis is provided for better understanding and planning of the experimental tests.
