    Thermal conductivity ofn-Tetracosan around the liquid-liquid transition temperatureT u (1985)
    Springer
    Colloid & polymer science 263 (1985), S. 603-606 
    Details
    ISSN: 1435-1536
    Keywords: n-Tetracosan ; thermal conductivity ; transient hot strip ; liquid-liquid transition
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract Forn-Tetracosan the temperature dependence of the thermal conductivity has been determined between 52 °C and 150 °C by the transient hot strip method. A decreasing thermal conductivity is followed by a constant one forT≳100 °C. The change in slope can be well estimated by using data of Brillouin scattering and specific volume measurements thus confirming the existence of theT u -phenomenon.

    Notes: Abstract Code provisions covering the installation of low voltage cables in plenum spaces above suspended ceilings used for environmental air are reviewed. A calculation procedure which could be used to estimate the potential toxicity of the decomposition products from these cables relative to the toxicity of the compartment fire necessary to decompose the cable insulation is presented. These estimates are used in a four-step procedure for estimating Smoke Toxicity Hazard proposed by the NFPA Toxicity Advisory Committee which is described. Example calculations for some typical cases and a discussion of their limitations are included.

    Fire resistance of wood structures (1985)
    Springer
    Fire technology 21 (1985), S. 34-40 
    Details
    ISSN: 1572-8099
    Keywords: Firesafety ; charcoal layer ; thermal conductivity ; pyrolysis ; oxygen diffusivity ; exothermic oxidation ; combustible gases ; load bearing ; flexural failure ; insulation ; joints
    Source: Springer Online Journal Archives 1860-2000
    Topics: Architecture, Civil Engineering, Surveying
    Notes: Abstract Wood as a building material has the disadvantage of being combustible. Consequently wood structures are seen by many as creating an environment less safe than structures built of noncombustible materials such as steel and masonry. However, experience has shown that some wooden structures have a fire resistance comparable, or greater than that of many noncombustible alternatives. Some statistical figures are given comparing wood with other materials. The fire course and the burning mechanisms of wood are briefly discussed, as is the fire resistance of wood structures from different perspectives. Reference is also made to present research work.

    ISSN: 1572-9567
    Keywords: high pressure ; thermal conductivity ; vitreous boron trioxide
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The thermal conductivity, λ, of vitreous boron trioxide was measured, using a hot-wire procedure, from 170 to 570 K and under pressures of up to 1.7 GPa. The thermal conductivity at room temperature and zero pressure was found to be 0.52 W · m−1 · K−1. The values of the logarithmic pressure derivative, g = d(ln λ)/d(ln ρ), where ρ is the density, were found to be 1.1 for uncompacted glass and 0.7 for glass compacted to 1.2 GPa. The variation of λ with temperature at constant density was approximately linear, with a positive slope of 1.38×10−3W·m−1·K−2.

    Notes: Abstract The thermal conductivity of some molten salts was measured at atmospheric pressure, using the coaxial cylinder method. The pure compounds NaCO3, KNO3, and NaNO2, the equimolar mixture NaNO3-KNO3, and HITEC, which is a three-component mixture, NaNO3-NaNO2-KNO3 (0.07-0.40-0.53 in weight), were investigated. For mixtures, it was found that the experimental thermal conductivity coefficients are in agreement with calculated values using a simple linear mixing law. The thermal diffusivity was calculated and compared with experimental data.

    Thermal conductivity of carbon tetrafluoride with argon and helium (1985)
    Springer
    International journal of thermophysics 6 (1985), S. 3-20 
    Details
    ISSN: 1572-9567
    Keywords: argon mixture ; carbon tetrafluoride mixtures ; helium mixture ; statistical mechanics ; thermal conductivity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The paper presents new measurements of the thermal conductivity of the binary mixtures of carbon tetrafluoride with helium and argon. Measurements were performed in a transient, hot-wire instrument at a nominal temperature of 27.5°C and over a range of densities (pressure up to 12 MPa). The accuracy is estimated to be 0.4%, deteriorating to 0.7% around the critical density. The paper provides polynomial fits which represent the data with a standard deviation of 0.4%. An analysis in terms of the Monchick-Pereira-Mason theory, with the translational contributions computed on the basis of earlier measurements of the viscosity of these mixtures, leads to a reasonable representation of the composition dependence of the zero-density thermal conductivity; the collision numbers ζ ij are treated here as adjustable parameters to obtain an optimum fit for each mixture.

    Thermal conductivity and heat capacity of solid nabr under pressure (1985)

    International journal of thermophysics 6 (1985), S. 177-190 
    Details
    ISSN: 1572-9567
    Keywords: heat capacity ; high pressure ; sodium bromide (NaBr) ; thermal conductivity ; thermal expansivity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Using the transient hot-wire method, measurements were made for solid NaBr of both the thermal conductivity and the heat capacity per unit volume. The measurements were performed in the temperature range 100 to 400 K and at pressures up to 2 GPa. An adiabatic compression technique allowed the determination of the thermal expansivity as a function of pressure at room temperature. The heat capacity did not vary with pressure. Analysis of the thermal conductivity data showed that it can be described adequately by the Leibfried-Schlömann formula. For temperatures up to 400 K only acoustic modes needed to be taken into account. A small contribution of optic modes to the heat transport might be apparent at the highest temperatures.

    Keywords: alkanes ; hydrocarbons ; liquids ; mixing rule ; thermal conductivity ; transient hot-wire method
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The thermal conductivity of four pure normal paraffin hydrocarbons (C11, C14, C15, C16) and binary and ternary mixtures of three n-paraffin hydrocarbons (C7, C11, C16) have been measured in the temperature range from about 20 to 90°C at atmospheric pressure. Measurements have been performed with the aid of a fully automated transient hot-wire instrument. The accuracy of the reported data is estimated to be ±1.0 to ±1.5%. A new simple and practical equation, which can calculate the thermal conductivity of pure n-paraffin hydrocarbons (4≤n≤ 16) with the uncertainty of ±1%, has been correlated in terms of temperature and number of carbon atoms based on the present results including some other reliable data. Also, a mixing rule for the mixtures of n-paraffin hydrocarbons was proposed and was adequately confirmed by the present results within the experimental error.

    Notes: Abstract The thermal conductivity (λ) of solid NaF has been measured over the temperature (T) range 100–350 K and at pressures (P) up to 2.5 GPa, using the transient hot-wire method. Results for λ(T,P) could be described to a good approximation by the Leibfried-Schlömann formula. It was found that the isochoric temperature derivative of the thermal resistivity W (= λ−1) increased systematically with the mass ratio for the B1-type phases of the sodium and potassium halides.

    Thermal conductivity of methane for temperatures between 110 and 310 K with pressures to 70 MPa (1985)
    Springer
    International journal of thermophysics 6 (1985), S. 119-142

    Topics: Physics
    Notes: Abstract The paper presents new experimental measurements of the thermal conductivity of methane for 14 temperatures between 110 and 310 K with pressures to 70 MPa and densities from 0 to 30 mol · L−1. The measurements were made with a transient hot-wire apparatus and they cover a wide range of physical states including the dilute gas, the moderately dense gas, the near-critical region, the compressed liquid states, and the vapor at temperatures below the critical temperature. The new measurements are closely spaced in temperature and density to describe the thermal conductivity surface, in particular the critical enhancement which extends to the highest temperature measured. A fit of the thermal conductivity surface allows comparison of the present results to those of others. The comparison reveals several discrepancies inherent in the results of others and in an earlier correlation. The precision (2σ) of the methane measurements is between 0.5 on 0.8 % for wire temperature transients of 4 to 5 K, while the accuracy is estimated to be 1.6%.
