Joule–Thomson Inversion in Vapor–Liquid–Solid Solution SystemsInternational Journal of Thermophysics - Tập 30 - Trang 1130-1143 - 2009
Dan Vladimir Nichita, Jerome Pauly, Jean-Luc Daridon
Solid phase precipitation can greatly affect thermal effects in isenthalpic
expansions; wax precipitation may occur in natural hydrocarbon systems in the
range of operating conditions, the wax appearance temperature being
significantly higher (as high as 350 K) for hyperbaric fluids. Recently, methods
for calculating the Joule–Thomson inversion curve (JTIC) for two-phase mixtures,
and for three-ph... hiện toàn bộ
Influence of Spacer Systems on Heat Transfer in Evacuated GlazingInternational Journal of Thermophysics - - 2009
K. Swimm, H. Weinläder, H.-P. Ebert
One attractive possibility to essentially improve the insulation properties of
glazing is to evacuate the space between the glass panes. This eliminates heat
transport due to convection between the glass panes and suppresses the thermal
conductivity of the remaining low pressure filling gas atmosphere. The glass
panes can be prevented from collapsing by using a matrix of spacers. These
spacers, ho... hiện toàn bộ
Crystallization and fibril formation in polymersInternational Journal of Thermophysics - Tập 11 - Trang 225-237 - 1990
E. J. Clark, J. D. Hoffman
Solutions of crystallizable polymers subjected to orientation crystallize in a
fibrillar morphology if the polymer is solidified rapidly. The central core of
the polymer fibers consists of thin, extended chain crystallites interspersed
with disordered regions. The extended chain crystals are small fibrils having
diameters generally less than a few hundred angstroms, while the lengths are
usually n... hiện toàn bộ
Thermal Property Characterization of a Low Supercooling Degree Binary Mixed Molten Salt for Thermal Energy Storage SystemInternational Journal of Thermophysics - Tập 40 - Trang 1-12 - 2019
Y. Li, C. G. Wang, G. Y. Liu, Q. Z. Zhu, Z. Z. Qiu
In this paper, LiNO3–NaCl binary mixed molten salt with high phase change
enthalpy was selected as phase change materials (PCM). LiNO3 was used as the
main phase change material, and NaCl was used as the additional material to
change the properties and reduce the supercooling degree of molten salts.
LiNO3–NaCl binary mixed molten salts with different mass proportion were
prepared by static melting... hiện toàn bộ
Density and Viscosity of Mixtures of n-Hexane and 1-Hexanol from 303 to 423 K up to 50 MPaInternational Journal of Thermophysics - Tập 23 - Trang 1537-1550 - 2002
F. Audonnet, A. A. H. Pádua
Experimental results for the density and viscosity of n-hexane+1-hexanol
mixtures are reported at temperatures from 303 to 423 K and pressures up to 50
MPa. The binary mixture was studied at three compositions, and measurements on
pure 1-hexanol are also reported. The two properties were measured
simultaneously using a single vibrating-wire sensor. The present results for
density have a precision ... hiện toàn bộ
Microsecond Laser Polarimetry for Emissivity Measurements on Liquid Metals at High Temperatures—Application to TantalumInternational Journal of Thermophysics - Tập 23 Số 5 - Trang 1281-1291 - 2002
Pottlacher, G., Seifter, A.
The aim of this work was to determine accurate and reliable thermophysical
properties of liquid tantalum from melting up to temperatures of 5000 K.
Temperature measurements on pulse-heated liquid metal samples reported by
different authors have always been performed under the assumption of a constant
emissivity over the whole liquid range because of the lack of data for liquid
metals. The uncertai... hiện toàn bộ
Evaluation of Thermal Conductivity of Hyperstoichiometric UO2+x by Molecular Dynamics SimulationInternational Journal of Thermophysics - Tập 28 - Trang 661-673 - 2007
Sho Yamasaki, Tatsumi Arima, Kazuya Idemitsu, Yaohiro Inagaki
The thermal conductivity of UO2+x has been investigated by an equilibrium
molecular dynamics (EMD) simulation up to 2000 K using the Born–Mayer–Huggins
interatomic potential with the partially ionic model. In the present EMD system
with the Green–Kubo method, the thermal conductivity was determined by the
auto-correlation functions of energy and charge currents and the cross-coupling
term. The the... hiện toàn bộ
Toward a liquid-state theory with accurate critical-region behaviorInternational Journal of Thermophysics - Tập 6 - Trang 561-571 - 1985
J. S. Høye, G. Stell
A scaling-theory approach that yields the scaled thermodynamics in the critical
region as the solution of an ordinary differential equation is given, along with
a power-series “isocline” representation of the solution yielding a polynomial
fit of a high accuracy. A means of extending the approach to the whole
liquid-state region through a self-consistent integral equation for the radial
distributi... hiện toàn bộ
Photothermal deflection in a supercritical fluidInternational Journal of Thermophysics - Tập 16 - Trang 1439-1453 - 1995
M. E. Briggs, R. W. Gammon
Photothermal deflection is among the most sensitive techniques available for the
measurement of small, localized heating, such as that from the absorption of a
focused laser beam in the bulk or surface of a material. A thin optical probe
beam is deflected by the refractive-index gradients arising from the heating,
and the size of the deflection provides the measure of the heating. We describe
the ... hiện toàn bộ
