JOURNAL FREE ACCESSThe thermal conductivity of liquids and their mixtures is an important transport property required in the design and analysis of various heat transfer processes and is also interested in the clarification of the internal structures of liquids. Further, the requirements of accurate thermal conductivity data are recently increased with the development of technology. This paper reviews first the past investigations concerning with the measurement and prediction of thermal conductivity of liquid organic compounds. Further, our thermal conductivity data of hydrocarbons, alcohols and their mixtures are presented. Using the experimental results obtained, the predictive method is described briefly to present the thermal conductivities of pure liquids and their mixtures on the basis of the hole theory concept and the lattice model.View full abstractDownload PDF (1222K) -

JOURNAL FREE ACCESSThermal radiation of metallic materials are characterized by the three factors: electronic properties, effects of surface roughness, and effects of surface films and/or layers. The present study discusses the electronic properties for the purpose for radiation heat transfer estimation. A systematic method is proposed to describe the spectral and temperature dependence of optical constants, by revising an electronic theory with an engineering point of view. The method is examined for various kinds of transition metals and alloys at high temperatures.View full abstractDownload PDF (1130K) -

JOURNAL FREE ACCESSTime variations of temperature distribution across the rear face of a thin specimen are observed in the laser flash heat capacity measurement. The energy distribution of a laser beam is made uniform by transmitting the beam through an optical fiber In a limited area and time, the adiabatic boundary condition is set up with negligible radial heat loss in the thin specimen. A measuring method of local heat capacity is discussed.View full abstractDownload PDF (370K) -

JOURNAL FREE ACCESSThere appear many new materials and working fluids through the development of new technology related to aerospace, electronics etc., and some large science projects. It needs physical properties data of these materials in order to use them effectively. It is self-evident that a lack of thermal properties data has disturbed research and new technology development in many fields of machining, physical properties control and its application.
The needs of thermal properties data in various engineering fields were investigated by authorized researchers related to thermal properties of materials. This article reports investigating results of them. This work was supported by the science grant of Japanese Educational Ministory.View full abstractDownload PDF (1491K)
