Stochastic analysis of electromagnetic properties variations for composite mixtures

2009 IEEE Antennas and Propagation Society International Symposium, 2009
A sparse grid technique is used to accelerate the evaluation of the effects on inclusion electrical parameter variations on the overall mixture homogenized electrical properties. This technique can significantly reduce the CPU time and yet maintain the accuracy of the stochastic analysis.

Composition and thermodynamic properties of reacting mixtures

Journal of Physics D: Applied Physics, 1998
The composition and thermodynamic properties of products of the reaction were determined for the values of parameters , and in the pressure range 0.1-10 MPa and the temperature range 298.15-50 000 K. Reaction products for lower temperatures in the region considered form an ideal heterogeneous system in the state of thermodynamic equilibrium at constant

Influence of the Monomer Mixture Composition on Acrylate Membrane Properties

Materials Science Forum, 2000
Macroporous membranes were prepared by bulk radical polymerization. The effect of the addition of a third monomer on membrane permeability and porosity was investigated. It was established that there is a correlation between the initial composition of the monomer mixture and porosity properties (permeability) of the prepared membranes.

A law of mixtures for transport properties in binary particulate composites

Journal of Applied Physics, 1998
A connected-grain model was developed earlier to explain mechanical and thermal properties of porous ceramics and sedimentary rocks. We have now generalized this model for binary particulate composites, based on simulation of a connected-grain structure of individual components of the composites by randomly selecting individual grains and shrinking ...

Hydriding properties of a mechanically alloyed mixture with a composition Mg2Ni

International Journal of Hydrogen Energy, 1985
Hydriding properties of a mechanically alloyed 2Mg + Ni mixture have been investigated and compared with those of the Mg2Ni alloy prepared by melting and sintering. The mechanically alloyed 2Mg + Ni mixture was estimated as an excellent hydrogen storage material.

Insulation properties of nano- and micro-filler mixture composite

CEIDP '05. 2005 Annual Report Conference on Electrical Insulation and Dielectric Phenomena, 2005., 2005
This paper presents the electrical insulation properties of a newly-developed composite material comprising a nano- and micro-filler mixture. The filler mixture composite was made by dispersing layered silicate fillers and silica fillers in epoxy resin. The filler mixture composite had the same low thermal expansion as aluminum.

Preparation and properties of phase change temperature-tuned composite phase change material based on sodium acetate trihydrate–urea/fumed silica for radiant floor heating system

Applied Thermal Engineering, 2019
In this work, a novel phase change temperature-tuned composite phase change material (PCM) for the PCM floor was developed by using sodium acetate trihydrate-urea non-eutectic mixture as PCM and fumed silica (SiO2) as both supporting material and ...

Analyzing the composition-property diagrams of multicomponent liquid mixtures

Russian Journal of Physical Chemistry A, 2011
We consider the local regularities of the composition-intensive/specific property diagrams of multicomponent mixtures in which composition is a scalar function of a vector argument. A topographical method used in differential geometry is used to produce one-dimensional, two-dimensional, and three-dimensional scalar fields.

Microstructure, tensile and wear properties of a novel graded Al matrix composite prepared by direct energy deposition

Journal of Alloys and Compounds, 2020
A novel graded Al matrix composite (AMC) was prepared by direct energy deposition (DED) from the mixture of pure Al, Cr and Fe powders. From the perspective of a single molten pool, the microstructure consists of two regions: AMC region with coarse ...
