JOURNAL FREE ACCESSA newly developed high pressure thermal analysis installation was used for the investigation of the hydrogen-sorbing characteristics of the Mg-Ni alloy. This apparatus made possible to measure DTA and TG curves simultaneously under hydrogen pressures up to 50kgfcm-2. Pressure-composition isotherms for the Mg2Ni-H2 system were obtained by isothermal measurements. The isobaric thermal cycling experiments revealed a shift of the initiation temperature for the desorption which corresponded to the activation process of powdered samples from “deactivated” state by having been exposed in air to “activated” state.View full abstractDownload PDF (845K) -

JOURNAL FREE ACCESSRoles of thermal energy storage in energy systems are described. Among four concepts of thermal energy storage, latent heat-thermal energy storage has a few advantages such as high energy density and heat storage of high quality at a constant temperature. Latent heat-thermal energy storage depends on storage materials. Comprehensively evaluated thermodynamic data as well as cost data are applied to screening the materials. It is shown from the screening that there is no suitable single component materials over a temperature range from 300°C to 440°C. Thermodynamic background to search for suitable multi-component materials in the temperature range is discussed. An example of applying thermal analyses to experimental evaluation is finally shown.View full abstractDownload PDF (1001K) -

JOURNAL FREE ACCESSIn conjunction with increasing demands on the reliable information about the thermophysical properties of technically important fluids, the importance of the researches in the related fields has become more significant. In the present survey, some of the significance as well as the scope of the thermophysical properties research are described specifically with respect to the isobaric heat capacity of fluids.
Several typical flow calorimeters recently reported are introduced and surveyed, since the flow calorimetry is evaluated as the best method to determine the isobaric heat capacity of gases experimentally. Among them, a compact flow calorimeter designed and operated by the present authors is also included and explained. Not only the configuration of the calorimeter but also the available information about the respective experimental apparatuses are presented.View full abstractDownload PDF (1161K) -
