    Keywords: density ; isothermal compressibility ; Tait equation ; thermal conductivity ; thermal expansion coefficient ; toluene ; transient hot-wire method
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract New experimental data on the thermal conductivity and the density of liquid toluene are presented in the temperature range 0–100°C at pressures up to 250 MPa. The measurements of thermal conductivity were performed with a transient hot-wire apparatus on an absolute basis with an inaccuracy less than 1.0%. The density was measured with a high-pressure burette method with an uncertainty within 0.1%. The experimental results for both properties are represented satisfactorily by the Tait-type equations, as well as empirical polynomials, covering the entire ranges of temperature and pressure. Furthermore, it is found that simple relations exist between the temperature dependence of thermal conductivity and the thermal expansion coefficient, and also between the pressure dependence of thermal conductivity and the isothermal compressibility, as are suggested theoretically.

    Thermal conductivity of fourteen liquids in the temperature range 298–373 K (1982)
    Springer

    ISSN: 1572-9567
    Keywords: aromatic hydrocarbons ; cyclohexane ; n-alkanes ; phenyl halides ; thermal conductivity ; toluene ; transient hot-wire method
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract New experimental data on the thermal conductivity of 14 organic liquids at atmospheric pressure are presented in the temperature range from 25 to 100°C. The liquids measured are five n-alkanes (C6, C7, C8, C10, C12), cyclohexane, six aromatic hydrocarbons (benzene, ethylbenzene, o-, m-, p-xylenes, isopropylbenzene) and two phenyl halides (chloro-, bromobenzenes). The measurements were performed by a transient hot-wire method on a relative basis. The thermal conductivity of toluene, which was selected as a reference liquid, was determined on an absolute basis with another transient apparatus. The precision of the present experimental results is within ±1.2%. The uncertainty of the thermal conductivity values is estimated to be within ±2%; this includes the uncertainty of the values of toluene as the reference liquid. The experimental results for each liquid are represented satisfactorily by a linear equation in temperature. At a reduced temperature T/T c=0.5, thermal conductivity has a simple relation with the molar density for each homologous series of liquids.

    Development of a database system for the thermophysical properties of 340 pure fluids (1983)
    Springer
    International journal of thermophysics 4 (1983), S. 283-294 
    Details
    ISSN: 1572-9567
    Keywords: compressibility factor ; database system: density ; dielectric constant ; refractive index ; retrieval program ; specific enthalpy ; specific entropy ; specific heat capacity ; specific volume ; surface tension ; thermal conductivity ; vapor pressure ; viscosity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract A new database system was designed and constructed in order to provide the newest and most reliable numerical data on thermophysical properties of fluids to the scientific and technical community as quickly as possible. The database is concerned with 12 kinds of property data: density, specific volume, compressibility factor, vapor pressure, specific heat, specific enthalpy, specific entropy, viscosity, thermal conductivity, surface tension, refractive index, and dielectric constant of 340 pure fluids under all conditions of seven convenient physical states. Only the most probable data, which were critically evaluated in advance, are compiled as functions of temperature and pressure in the form of either numerical data tables or correlation formulas. Property values at desired grid points of temperature and pressure can be obtained in SI units directly or by interpolations with some supplementary information, such as the grade of reliability, source bibliography, and fundamental physical constants of the fluid. The database is usable as conversational processing by TSS, the tabulation of property data in a batch processing, and one of the subroutine libraries in the computation of a user's program. Ten kinds of application programs are prepared for multipurpose retrievals so that anyone can use the database without any special knowledge of the structure or machine languages of this system.

    Thermal conductivity of gaseous fluorocarbon refrigerants R 12, R 13, R 22, and R 23, under pressure (1981)

    Topics: Physics
    Notes: Abstract The thermal conductivity of four gaseous fluorocarbon refrigerants has been measured by a vertical coaxial cylinder apparatus on a relative basis. The fluorocarbon refrigerants used and the ranges of temperature and pressure covered are as follows: R 12 (Dichlorodifluoromethane CCl2F2): 298.15–393.15 K, 0.1–4.28 MPa R 13 (Chlorotrifluoromethane CClF3): 283.15–373.15 K, 0.1–6.96 MPa R 22 (Chlorodifluoromethane CHClF2): 298.15–393.15 K, 0.1–5.76 MPa R 23 (Trifluoromethane CHF3): 283.15–373.15 K, 0.1–6.96 MPa The apparatus was calibrated using Ar, N2, and CO2 as the standard gases. The uncertainty of the experimental data is estimated to be within 2%, except in the critical region. The behavior of the thermal conductivity for these fluorocarbons is quite similar; thermal conductivity increases with increasing pressure. The temperature coefficient of thermal conductivity at constant pressure, (∂λ/∂T) p , is positive at low pressures and becomes negative at high pressures. Therefore, the thermal conductivity isotherms of each refrigerant intersect each other in a specific range of pressure. A steep enhancement of thermal conductivity is observed near the critical point. The experimental results are statistically analyzed and the thermal conductivities are expressed as functions of temperature and pressure and of temperature and density.

    ISSN: 1434-601X

    Topics: Physics
    Notes: Abstract The level structure of90Y has been studied using the91Zr(t,α)90Y and89Y(n,γ)90Y reactions. The proton pickup reaction was studied with 17 MeV tritons and a Q3D spectrometer. In the thermal89Y(n, γ)90Y reactionγ-rays from ≈100 to 6,857 keV were observed. In addition to previously known states and configurations, the ten states of theπ(p 3/2)−1 v(d 5/2)1 andπ(f 5/2)−1 v(d 5/2)1 configurations are assigned. Also many other new levels are identified from the (n, γ) data. The 0−state of theπ(f 5/2)−1 v(d 5/2)1 is assigned at 3,130keV. Finite-range shell model calculations suggest that the tensor force is necessary to reproduce the experimentally observed splittings.
