An investigation of heat transfer gain with introduction of graphite powder to helium gas
(1993)Analysis is made of heat transfer by turbulently flowing helium gas with suspended graphite particles in a circular pipe. At very high temperatures, the radiative heat to gas alone can be profoundly improved because of the ... -
Numerical computation of turbulent flow in pipes
(1993)Developing turbulent flow in pipes of circular cross-section with length-to-diameter ratio of 100 has been computed at eight Reynolds numbers ranging from 3.8 X10 "SUP 4" to 3.88 X10 "SUP 5" . Numerical solutions of the ... -
Distributions of Compressive Strength Obtained from Various Diameter Cores
(Amer Concrete Inst, 2012)Test results from cores with diameters smaller than the standard sizes and with length-to-diameter (Vd) ratios less than I are considered to be unreliable due to higher variability in concrete strength. There is, however, ... -
Influence of tantalum additions on the microstructure and shape memory response of Ti50.5Ni24.5Pd25 high-temperature shape memory alloy
(Elsevier Science Sa, 2014)A Ti50.5Ni24.5Pd25 (at%) high-temperature shape memory alloy (HTSMA) was alloyed with 1, 3, and 5 at% Ta additions in an effort to enhance the shape memory properties, particularly the dimensional stability for actuator ... -
Engineering electronic properties of metal-MoSe2 interfaces using self-assembled monolayers
(Royal Soc Chemistry, 2014)Metallic contacts are critical components of electronic devices and the presence of a large Schottky barrier is detrimental for an optimal device operation. Here, we show by using first-principles calculations that a ... -
Assessment on lattice thermal properties of two-dimensional honeycomb structures: Graphene, h-BN, h-MoS2, and h-MoSe2

Ab initio calculations of martensitic phase behavior in Ni2FeGa magnetic shape memory alloys
(Elsevier Science Sa, 2014)A series of spin polarized energy calculations based on density functional theory (DFT) have been carried out to investigate the structural, magnetic, electronic and mechanical properties of Ni2FeGa magnetic shape memory ... -
Equilibrium limit of thermal conduction and boundary scattering in nanostructures
(Amer Inst Physics, 2014)Determining the lattice thermal conductivity (kappa) of nanostructures is especially challenging in that, aside from the phonon-phonon scattering present in large systems, the scattering of phonons from the system boundary ... -
Mechanical and thermal properties of h-MX2 (M = Cr, Mo, W; X = O, S, Se, Te) monolayers: A comparative study
(Amer Inst Physics, 2014)Using density functional theory, we obtain the mechanical and thermal properties of MX2 monolayers (where M = Cr, Mo, W and X = O, S, Se, Te). The C-centered phonon frequencies (i.e., A(1), A(2)'', E ', and E ''), relative ... -
