[1] A method for combining satellite altimetry observations with satellite measurements of the Earth’s time-varying gravity to give improved estimates of the ocean’s heat storage is presented. Over the ocean the time-variable component of the geoid can be related to the time-varying bottom pressure. The methodology of estimating the ocean’s time-varying heat storage using altimetric observation...
Two figures of merit for hybrid Thermal Energy Storage (TES) units are developed: the volumetric figure of merit, V~ , and the temperature control figure of merit, T~ ∆ . A dimensional analysis shows that these quantities are related to the performance specification of the storage unit and its physical design. A previously benchmarked semi-empirical finite volume model is used to study the char...
During exercise in the heat, sweat output often exceeds water intake, resulting in a body water deficit (hypohydration) and electrolyte losses. Because daily water losses can be substantial, persons need to emphasize drinking during exercise as well as at meals. For persons consuming a normal diet, electrolyte supplementation is not warranted except perhaps during the first few days of heat exp...
Recent reviews of the literature on thermoregulation during exercise including the regulation of thermal sweating have been made by many scientists [see (1) for Jessen's review]. Human body temperature is determined by the balance between heat accumulation, whether generated by physical activity (metabolic heat production) or gained from the environment (environmental heat), and heat dissipatio...
STATEMENT OF PROBLEM Poor wettability of denture relining materials may lead to retention problems and patient discomfort. PURPOSE Purpose of this study is to compare and evaluate wettability of nine denture relining materials using contact angle measurements under air and water storage over time. MATERIAL AND METHODS Nine denture relining materials were investigated in this study. Two heat...
Air quality inside the residential buildings has become a major challenge due to the climatic change and increasing the living standards. The increased cooling demand results a peak in electrical power consumption during the hottest summer hours. Phase Change Materials (PCMs) used in Thermal Energy Storage (TES) systems, can be a proper solution to control the room temperature and maintain the ...
sometimes unexpected results which have emerged, and looks to future developments. This paper describes the simulation of electric storage heaters and their controls. A method for modelling manual control, inferred from transformer readings, is described. Use of the dynamic simulation language ESL compiled into a single program with an existing building simulation program, is explained. This pr...
To realize the lagging behavior in heat conduction observed in these two decades, this paper firstly theoretically excludes the possibility that the underlying thermal inertia is a result of the time delay in heat diffusion. Instead, we verify in experiments the electro-thermal analogy, wherein the thermal inertial is parameterized by thermal inductance that formulates hyperbolic heat-conductio...
