In the current research, thermal conductivity of magnetite (Fe3O4) has been calculated using molecular dynamic simulation. The rNEMD Molecular Dynamics Method provided in the LMMPS package is used for the simulation of the thermal conductivity. The effects of magnetite layer size and temperature on the thermal conductivity have been investigated. The numerical results have...
The present article is aimed at study on agroclimatic conditions of cultivation of sunflower throughout selected substations at Kurdistan Province by means of GIS system. In this investigation, meteorological data have been received from synoptic stations based on daily, monthly, and annually trend from Iran Meteorological Organization (IMO) at Kurdistan Province and then homogeneity of data ...
Results of laboratory tests on specimens produced from subsoil studies were evaluated tocharacterize geotechnical properties of Tabriz Marl. It was concluded that, Tabriz Marl may be considered as a high liquid limit silt or clay (MH & CH). Range of changes of index, physical and mechanical properties of the Tabriz Marl are comparatively vast. Correlation between these properties has been intro...
the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
In this paper, we study the plasmonic thermal conductance of ordered stacks of metallic nanorings in a host material. Using second quantized formalism of the Random Phase Approximation, we first determine the dispersion relations of surface plasmon waves on the stacks of nanorings. Then, using Landauer-Buttiker formalism, we determine the coefficient of plasmonic thermal conductance and heat cu...
classical trajectory (monte carlo) calculation is used to calculate collision rate constants of ion-quadrupolar molecule interactions for the h¯+c2h2 system. the method presented here takes into account the effect of the induced dipole-induced dipole potential on ion-quadrupolar molecule collision rate constants. it is also assumed that the colliding particles have a definite size. the thermal ...
Graphene has received much attention due to its remarkable electronic properties. It also has exceptional thermal properties, such as an unusually high thermal conductivity. Understanding thermal transport of graphene is of great importance to the applications for future graphene‐based devices in energy efficient nanoelectronics. We have calculated the thermal current of symmetric...
graphene oxide was prepared using modified hummers method. stable ethylene-glycol nanofluids containing graphene oxide nanosheets were provided. nd: yag pulsed laser was applied to prepare reduced nanofluids. experimental results revealed that thermal conductivity of the nanofluids is increased with increasing the concentration of graphene oxide (go) in ethylene glycol. the enhancement ratio of...
When graphene is shrunk into ~10 nm scale graphene nanoribbons or nanomesh structures, it is expected that not only electrical properties but also thermal conductivity and thermoelectric property are significantly altered due to the quantum confinement effect and extrinsic phonon-edge scattering. Here, we fabricate large-area, sub10 nm singleand bilayer graphene nanomeshes from block copolymer ...
Several heat transfer problems related to single-walled carbon nanotubes (SWNTs) are considered using molecular dynamics (MD) simulations. The Brenner potential [1] with the simplified form [2] is employed as the potential function between carbon and carbon within a nanotube. MD simulations of thermal conductivity along a nanotube, isotope effect in longitudinal thermal conductivity, and therma...
