It is shown that Cε and Cεθ are approximately equal in the near-equilibrium region (viz., y+ = 100 to y/h = 0.7) where the production and dissipation rates of either the turbulent kinetic energy or scalar variance are approximately equal and the magnitudes of the diffusion terms are negligibly small. The magnitudes of Cε and Cεθ are about 2 and 1 in the logarithmic and outer regions, respectively, when h+ is sufficiently large. The former value is about the same for the channel, pipe, and turbulent boundary layer, reflecting the similarity between the mean velocity and temperature distributions among these three canonical flows. The latter value is, on the other hand, about twice as large as in homogeneous isotropic turbulence due to the existence of the large-scale u structures in the channel. The behaviour of Cε and Cεθ impacts on turbulence modeling. In particular, the similarity between Cε and Cεθ leads to a simple relation for the scalar variance to turbulent kinetic energy time-scale ratio, an important ingredient in the eddy diffusivity model. This similarity also yields a relation between the Taylor and Corrsin microscales and analogous relations, in terms of h+, for the Taylor microscale Reynolds number and Corrsin microscale Peclet number. This dependence is reasonably well supported by both the DNS data at small to moderate h+ and the experimental data of Comte-Bellot [Ph. D. thesis (University of Grenoble, 1963)] at larger h+. It does not however apply to a turbulent boundary layer where the mean energy dissipation rate, normalized on either wall or outer variables, is about 30% larger than for the channel flow. © American Institute of Physics]]> Wed 11 Apr 2018 11:45:27 AEST ]]> Effectiveness of a multi-strategy intervention in increasing the implementation of vegetable and fruit breaks by Australian primary schools: a non-randomized controlled trial https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:12898 Wed 11 Apr 2018 11:14:00 AEST ]]> Modelling of heat and mass transport in composite materials https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:4265 Wed 11 Apr 2018 11:02:22 AEST ]]> The computations that support simple decision-making: a comparison between the diffusion and urgency-gating models https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30938 Wed 11 Apr 2018 10:38:07 AEST ]]> The lattice Monte Carlo method for solving phenomenological mass and thermal diffusion problems https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:4413 Wed 11 Apr 2018 10:11:57 AEST ]]> Recent progress in the simulation of diffusion associated with hollow and bi-metallic nanoparticles https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:8239 Wed 11 Apr 2018 09:46:23 AEST ]]> Theoretical analysis and atomistic modelling of diffusion and stability of pure element hollow nanospheres and nanotubes https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:4414 Wed 11 Apr 2018 09:25:06 AEST ]]> Predicting gully erosion using landform evolution models: Insights from mining landforms https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:43980 Wed 07 Feb 2024 16:38:20 AEDT ]]> Diffusion of Integrated Reporting, Insights, and Potential Avenues for Future Research https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50092 Wed 07 Feb 2024 14:31:58 AEDT ]]> Modelling evaporation of mono and binary component alkane droplets in different convective flow conditions. https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:26042 Wed 04 Sep 2019 12:17:30 AEST ]]> A review of moisture migration in bulk material https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37429 Wed 02 Dec 2020 11:02:10 AEDT ]]> Cocrystals of apixaban with improved solubility and permeability: Formulation, physicochemical characterization, pharmacokinetic evaluation, and computational studies https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46309 Tue 15 Nov 2022 10:28:48 AEDT ]]> Atomistic origin of the thermodynamic activation energy for self-diffusion and order-order relaxation in intermetallic compounds II: Monte Carlo simulation of B2-ordering binaries https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33512 Tue 13 Nov 2018 13:07:00 AEDT ]]> Diffusion: Isotope Effect and Manning Factor in Liquids https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52360 Tue 10 Oct 2023 11:42:36 AEDT ]]> A new approach for analysing interdiffusion in multicomponent alloys https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:42875 2) systems.

While the tracer diffusion coefficients at the equilibrium state predicted by Green-Kubo and the Einstein equations follow the Arrhenius relationship and agree well with the experimental and theoretical results, a linear relationship between the logarithm of tracer diffusion coefficients and the external pressure is addressed in term of an activation volume modified Arrhenius relations. It is understood that the autocorrelation velocity functions (VACF) characterizes the capacity of an atom memorizing the velocity, which has also been considered as one of important approaches revealing thermodynamics, kinetics and structure relaxation dynamics of melts. The onset of the negative region of VACF is in line with the plateau of the meaning square displacement representing the cage effect of the system. The initial damping oscillations of VACFs are due to the momentum relaxation caused by the collision between the tagged atoms and its neighbor ones while the subsequent rises result from the energy relaxation. This work provides an insight into the physical factors controlling these dynamic behaviors under extreme conditions of Ni-Al, which could be extended to the other advanced materials.]]> Mon 17 Oct 2022 09:38:37 AEDT ]]> Diffusive resettlement: Irreversible urban transitions in closed systems https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:41602 Mon 08 Aug 2022 09:21:19 AEST ]]> Liquid-phase water isotope separation using graphene-oxide membranes https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45805 Mon 07 Nov 2022 10:26:06 AEDT ]]> The Manning factor for direct exchange and ring diffusion mechanisms https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33291 Fri 28 Sep 2018 15:54:20 AEST ]]> Investigation of the leaching behavior of lead in stabilized/solidified waste using a two-year semi-dynamic leaching test https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33284 Fri 28 Sep 2018 15:47:21 AEST ]]> Relationships between chemical and tracer diffusion coefficients in strongly ionic crystals https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:53023 Fri 17 Nov 2023 11:30:04 AEDT ]]> Molecular versus crystallite PCBM diffusion in P3HT:PCBM blends https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:26350 Fri 10 Nov 2023 15:51:34 AEDT ]]> An analytical solution for charge carrier densities in dye-sensitized solar cells https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:36758 Fri 03 Jul 2020 11:25:43 AEST ]]>
