The deviation of density and viscosity values oil mixtures from those calculated according to the additivity rule has been examined. Mathematical models have developed for determining properties with different compositions taking into account group composition source components. Mixtures containing components a high content alkanes low arenes found be characterized by extreme deviations towards...

this study was conducted in order to evaluate the effects of long term ageing on toughness andresilient modulus of asphalt concrete mixtures containing electric arc and basic oxygen furnacesteel slags. after initial evaluation of the properties of steel slags using x-ray diffraction andscanning electric microscope, eleven sets of laboratory mixtures were prepared. each set wastreated replacing ...

Abstract Current multi-component, multiphase pseudo-potential lattice Boltzmann models have thermodynamic inconsistencies that prevent them to correctly predict the phase behavior of partially miscible multi-component fluids, such as hydrocarbon mixtures. This paper identifies these and attempts design a thermodynamically consistent model allows mass transfer across interfaces is capable typica...

Recently developed analytic approximation for the equation of state of fully ionized nonideal electron-ion plasma mixtures [A. Y. Potekhin, G. Chabrier, and F. J. Rogers, Phys. Rev. E 79, 016411 (2009)], which covers the transition between the weak and strong Coulomb coupling regimes and reproduces numerical results obtained in the hypernetted-chain (HNC) approximation, is modified in order to ...

In this article, we highlight new developments and recent studies concerning adverse human health effects related to chemical mixtures. One group of activities comprises the development of a new computer program for analyzing mixture studies and a mathematical model as a basis for combination rules that predict the toxicity of mixtures. Other new activities in the area of experimental studies a...

In recent years, binary mixtures have been the subject of numerous experimental and numerical studies. However, few attempts made on investigating effect fines content (fc) non-associated plasticity mixtures, which is significant for constitutive modelling such material. Thanks to 2D DEM simulations, this study aims provide an understanding how fc affects character flow rule resulting material ...

In this Brief Report we investigate the multiscale hydrodynamical response of a liquid as a function of mixture composition. This is done via a series of molecular dynamics simulations in which the wave-vector-dependent viscosity kernel is computed for three mixtures, each with 7-15 different compositions. We observe that the viscosity kernel is dependent on composition for simple atomic mixtur...

The modern engineering structures require the advanced engineering materials to resist the high temperatures and to provide high stiffness. In particular the functionally graded porous materials (FGPMs) introduced are expected to have these desired properties, consequently eliminating local stress concentration and de-lamination. In the present paper, a new shear strains shape function is chose...

In this article, we examine the elastic properties of boron-nitride nanotubes, which are embedded in amorphous silicon-boron-nitride ceramics. We employ molecular dynamics simulations using the Parrinello-Rahman approach. To this end, all systems are modeled with a reactive many-body bond order potential due to Tersoff, which is able to describe covalent bonding accurately. We apply external st...
