The dynamic thermophysical properties evolution and multi-scale heat transport mechanisms of 2.5D C/SiC composite under high-temperature air oxidation environment

The variations in thermophysical properties and dynamic heat transfer mechanism of 2.5D C/SiC ceramic matrix composites (2.5D C/SiC-CMC) under a high-temperature air oxidation environment are investigated by experiments and numerical simulations. A new multi-scale thermal analysis model of 2.5D C/SiC-CMC under high-temperature oxidation is proposed to predict its equivalent thermal conductivity and analysis its multi-scale heat transport mechanisms. The multi-scale thermal analysis model is developed by blending the multi-scale asymptotic thermal analysis method and oxidation kinetics theory, which includes the micro-scale model and mesoscale model. The micro-scale model simulates the oxidation process of the carbon fibers and PyC interface through oxidation kinetics, which predicts the varying equivalent thermal conductivity of yarns with oxidation. The mesoscale model is constructed based on the experimental statistics which reflect the multi-scale structure within the 2.5D C/SiC-CMC with oxidation. The mesoscale model introduces oxidation characteristics by considering dynamic variations in yarn thermal properties. The dynamic thermophysical properties of the 2.5D C/SiC-CMC with oxidation are tested in the experimental study, which verifies that the multi-scale thermal analysis model has highlighted prediction accuracy. The results show that high-temperature oxidation causes significant variations in the dynamic thermal behavior of 2.5D C/SiC-CMC which is critical for the practical thermal protection design of 2.5D C/SiC-CMC hot components in engineering applications.

Homotopy analysis approach to Ferro-hydrodynamic bio-nanofluid flow over a co-axial rotating discs with Stefan blowing and magnetic dipole

In this study, the Homotopy Analysis Method (HAM) is employed to investigate the flow of a Ferro-hydrodynamic bio-nanofluid over a co-axial rotating disks with Stefan blowing, magnetic dipole, and hall effects. The heat transport mechanism is modeled by using the Brownian movement and thermophoresis. The governing equations are derived and transformed into nondimensional form using appropriate similarity transformations. The resulting equations are solved analytically using the Homotopy Analysis Method. The obtained results are compared with the existing literature and are found to be in excellent agreement. The effects of various parameters such as Hartmann number (Ha), Ferro-hydrodynamic interaction parameter (B), Stefan blowing effect Peclet (Pe), and bio-convection Lewis number (Lb) are examined via graphical representation. Moreover, the bio-nanofluid radial velocity field is enhanced by improving the values of hall and Ferro-hydrodynamic interaction parameter (FHD). The temperature profile is diminished due to increasing the values of hall parameter, while the opposite behavior is observed when rising the values of FHD parameter. Increasing the Hartmann number (Ha) lead to decline the radial and tangential velocity, whereas the temperature profile is enhanced. The motile microorganisms filed is significantly affected by bio-Lewis and Peclet numbers. The significance of Stefan blowing is discussed on the hydrodynamic, heat, and mass transport aspects for the instances of fw = 0, and respectively. Also, the drag coefficient, heat and mass transport, motile microorganisms rates are discussed via tables.

Dynamics of Williamson Hybrid Nanofluid Over an Extending Surface with Non-Linear Convection and Shape Factors

Combined effects of the magnetic field, heat source/sink, and homogeneous–heterogeneous chemical reaction on the three-dimensional fluid flow over a stretching sheet have been examined in this paper. For originality and practicality, the influence of non-linear convection on hybridised nanoparticles of titanium dioxide (TiO2) and silver (Ag) in the non-Newtonian engine oil (EO) are introduced into the governing equations, which are then dimension-free by utilizing appropriate transformations. Williamson fluid model has been employed to determine the rheological features of the considered fluid mixture. MATLAB inbuilt bvp4c solver and Keller box method are proposed for the numerical solution of current fluid theories. Physical elaboration of the graphs is given to recognize the influence on fluid flow and heat transport mechanism in different rising conditions. Based on results, the implication of magnetic field and Williamson parameters restrict the fluid flow for both nanofluid (TiO2/EO) and hybrid nanofluid (TiO2 + Ag/EO). Special case studies of the shape factor effect show more enhancement in heat transfer rate for cylindrically shaped nanoparticles 25.8162% followed by brick-shaped 20.3286% and spherical-shaped 17.0583%. This study will provide better insight into applications including aircraft refrigeration, lubrication, plastic processing, engine and generator cooling, and so forth.

Study the effects of temperature and strain rates on transient thermomechanical responses on multilayer skin tissue

The present study is focused on understanding the effects of strain and temperature rates on heat transport mechanisms and the related thermo-mechanical interaction with skin tissue, which are essential for the effective application of thermal therapeutic techniques. The goal of this article is to develop a mathematical framework to investigate the thermo-mechanical phenomena occurring on triple-layered skin tissue using the Modified Green-Lindsay model (MGL) by taking into consideration of two thermal relaxation parameters. This model takes into consideration the effect of strain and temperature rate factors in thermoelastic behaviour which was neglected in several other thermoelastic models. The problem is formulated in a unified way to derive the governing equations and constitutive relations under the present model and also the thermoelasticity with two phase-lag parameters. A comprehensive assessment of solution is discussed for MGL model and compared the results with the corresponding results predicted by dual phase lag generalized thermoelastic model that involves two phase-lags. The effect of strain rate term in heat transport on skin tissue are especially highlighted.

Analytical model for two-channel phonon transport engineering

The reduction of vibrational contributions to thermal transport and the search for material classes with intrinsically low lattice thermal conductivities are at the heart of thermoelectric research. Both engineering the heat transport of known thermoelectrics and searching for new material candidates is guided by understanding the physics of low thermal conduction. Spectral analytical models (e.g., the Callaway model) for propagating phonon transport have proved to be a powerful tool for interpreting experimental results and providing metrics for materials design. Now, however, it is known that another mechanism of phonon heat transport can occur in complex crystalline materials. Called diffusons, they describe the non-propagating atomic scale random-walk of thermal energy between energetically proximal phonon modes. While analytical models exist to describe both transport behaviors independently, an analytical model accounting for both transport channels simultaneously is necessary to interpret and design so-called 2-channel thermal transport. In this work, we propose an analytical 2-channel transport model that partitions the vibrational density of states into two transport regimes and subsequently accounts for both transport mechanisms. The model is then used to explain the experimental thermal conductivities of the solid solution series Ag9-xGa1-xGexSe6. In this series, substitution leads to the stabilization of a highly vacant Ag+ substructure, which is expected to induce strong point-defect phonon scattering. While the propagating phonons are strongly scattered at low temperatures, the diffuson channel is apparently unaffected. By establishing materials design metrics for 2-channel thermal transport from analytical theory, experimental investigations of materials with astonishingly low lattice thermal conductivities can now be better guided and informed.

Investigation of quadratically stratified squeezed Casson fluid flow with slip features over a convectively heated surface

There are diverse engineering and industrial related dynamical systems where the dissipative phenomenon in non-Newtonian fluids have given great significance. Example includes aerodynamics heating process, flows of polymer processing (injection molding, extrusion, etc.), and flow of fluid in small devices under associated heat transport process. Here, this attempt presents an analytical study of the squeezing mechanism. The squeezed material is presented utilizing the Casson incompressible fluid model. Viscous dissipation impacts along with convective surface conditions are retained in this study. A slip and stratification analysis in respect of unsteady flow, heat and mass transfer is performed in this attempt. The governing equations under the squeezing process are made first simplified and then transformed into dimensionless form using the similarity variables. Here, homotopic technique has been implemented in order to solve the dimensionless equations. Outcomes of velocity, heat, and mass transport mechanisms are discussed graphically in detail against pertinent parameters. In this analysis the heat and mass transport increases with increasing thermal and solutal Biot number, however the velocity decrements near the sheets as the slip parameter increases. Moreover, study concludes that squeezing mechanism intensifies the flow velocity. Phenomenon of squeezing experiences numerous industrial related processes such as mechanisms of lubrication, engine cooling system, designing permeable surfaces to minimize drag, etc., Force of drag is decreased further because of squeezing parameter. Therefore, because of low drag force, minimum amount of energy related resources can be utilized.

The through-thickness thermal conductivity and heat transport mechanism of carbon fiber three-dimensional orthogonal woven fabric composite

This paper successfully constructed a high through-thickness thermal conductivity carbon fiber composite with three-dimensional orthogonal woven fabric (3DOWF) by taking advantage of the high conductivity of carbon fiber. The effect of structural parameters and Z-direction bundling yarn (Z-yarn) on thermal conductivity (TC) was investigated, and thermal transport mechanism was analyzed. The results show that the TC in the through-thickness direction of 3DOWFs increase dramatically after adding Z-yarn structure, reaching up to 4.12 W/m/K, which is 116% higher than the laminated sample. A plane heat source was established to record the temperature-time curves of the composites, and results show that the composites with higher TC have faster equilibrium time and higher equilibrium temperature. Infrared thermography demonstrates the difference of thermal response process between 3DOWF and laminated material. To sum up, a large amount of heat energy can be transferred rapidly from hot surface to cold one through these Z-yarn paths in the thermal conductive network of 3DOWF, which has potential application in composite with high thermal conductivity.

Investigation on transport properties and anomalously heat-carrying optical phonons in KXY (X = Ca, Mg; Y = Sb, Bi)

In this work, we systematically studied the thermal transport properties of ternary zintl compound KXY using self-consistent phonon theory combined with compressive sensing technology and the Boltzmann transport equation. The effects of quartic anharmonic induced phonon renormalization and 4 - phonon scattering on the results are fully considered. Vibrational mode visualization reveals that the anomalous contribution of optical phonons to lattice thermal conductivity in KCaBi originates from high-speed out-of-phase vibrations of Ca atoms. We analyzed the microscopic mechanism of heat transport from the perspective of atomic bonding combined with the results of group velocity, scattering rate, Gru¨neisen parameter, mean free path, etc. In addition, we verified and predicted the mechanical properties in KXY by calculation.

Heat transport mechanism in glycerin-titania nanofluid over a permeable slanted surface by considering nanoparticles aggregation and Cattaneo Christov thermal flux.

The dynamics of superior heat transport fluids are of much interest and dominant over traditional fluids. Applications of such fluids can be found in advanced medical sciences, to maintain the building temperature, environmental sciences, chemical engineering, food engineering, and other applied research areas where enhanced heat transfer is required. The major aim of this research is to report the thermal performance of the Glycerin-titania nanofluid using a thermal conductivity model comprising the effects of nanoparticles aggregation, and CCTF over a permeable slanted surface. The enhanced heat transport model was then analyzed numerically via RK scheme and furnished the outcomes with graphical aid under the variations of physical parameters. It is examined that the addition of CCTF (A1) in the model potentially contributes to thermal performance of aggregated nanofluid. The temperature enhances for injecting fluid from the surface and reduces due to strong suction. Further, the fluid particles attained maximum velocity for at the surface and it shows asymptotic behavior far from the working domain.

Towards a novel EMHD dissipative stagnation point flow model for radiating copper-based ethylene glycol nanofluids: An unsteady two-dimensional homogeneous second-grade flow case study

A novel EMHD dissipative second-grade nanofluid flow model is proposed exclusively in this numerical inspection for radiating copper-based ethylene glycol nanofluids to reveal the dynamical and thermal aspects of the studied homogeneous mixture during its unsteady two-dimensional stagnation point flow towards a horizontal electromagnetic actuator. Based on admissible physical assumptions and authenticated experimental correlations, the governing PDEs and BCs are derived appropriately for the nanofluid flow problem under consideration. After numerous rearrangements and non-dimensionalization treatments, the resulting ODEs and BCs are handled computationally with the help of a robust GDQ algorithm under the parametric control of several influencing factors, whose strengthening magnitudes affect probably the flow control process and heat transport mechanism. In this context, it proved graphically that the nanoparticles’ loading process exhibits dissimilar dynamical and thermal impacts as compared with the influences of the nanoparticles’ diameter size. Besides, the resistive dynamical effect of the utilized electromagnetic actuator reinforces thermally the enhancing role of the thermal radiative heat flux and Joule’s heating process within the nanofluidic medium.

The Microzone Structure Regulation of Diamond/Cu-B Composites for High Thermal Conductivity: Combining Experiments and First-Principles Calculations

The interface microzone characteristics determine the thermophysical properties of diamond/Cu composites, while the mechanisms of interface formation and heat transport still need to be revealed. Here, diamond/Cu-B composites with different boron content were prepared by vacuum pressure infiltration. Diamond/Cu-B composites up to 694 W/(mK) were obtained. The interfacial carbides formation process and the enhancement mechanisms of interfacial heat conduction in diamond/Cu-B composites were studied by HRTEM and first-principles calculations. It is demonstrated that boron can diffuse toward the interface region with an energy barrier of 0.87 eV, and these elements are energetically favorable to form the B4C phase. The calculation of the phonon spectrum proves that the B4C phonon spectrum is distributed in the range of the copper and diamond phonon spectrum. The overlapping of phonon spectra and the dentate structure together enhance the interface phononic transport efficiency, thereby improving the interface thermal conductance.

The MHD graphene−CMC−water nanofluid past a stretchable wall with Joule heating and velocity slip impact: Coolant application

The heat transport mechanism has an engrossing application in effective heat management for the automobile industry and the biomedical industry. The analysis of the MHD graphene−carboxymethyl cellulose (CMC) solution−water nanofluid past a stretchable wall with Joule heating and velocity slip impact is performed in this regard. A graphene-based nanofluid is considered. The dynamic model is used to simplify the complicated ordinary differential equations into non-dimensional forms, which are then evaluated analytically. Numerical data and graphs are produced to analyze the consequences of a physical entity with the aid of Maple 17. Moreover, the velocity field is decreased, while the magnitude of the magnetic parameter is increased. A decrease in θ(η) is observed as a result of an increase in ϕ. It is noted that a rise in the magnetic parameter causes a fall in the temperature distribution. It is perceived that −f′′(0) is decreased with an augmentation in βs, and an opposite trend is shown for ϕ. The velocity profile is the growing function of Mgn, βs, and Kve, with the reversed mode shown in case of ϕ. The temperature profile is the declining function of Pr, Ecrt, ϕ, and χ, with a contradictory trend observed for Mgn and βs. The flow regime is displayed against the viscoelastic parameter.

How temperatures derived from fluid flow and heat transport models impact predictions of deep geothermal potentials: the “heat in place” method applied to Hesse (Germany)

One key aspect in the energy transition is to use the deep geothermal energy stored in sedimentary basins as well as in igneous and metamorphic basement rocks. To estimate the variability of deep geothermal potentials across different geological domains as encountered in the Federal State of Hesse (Germany), it is necessary to understand the driving processes of fluid flow and heat transport affecting subsurface temperature variations. In this study, we quantify the stored energy in a set of geological units in the subsurface of Hesse with the method of “heat in place” (HIP, sensu Muffler and Cataldi in Geothermics 7:53–89, 1978)—HIP is one proxy for the geothermal potential of these units controlled by their temperature configuration as derived from a series of coupled 3D thermo-hydraulic numerical models. We show how conductive, advective and convective heat transport mechanisms influence the thermal field and thereby the HIP calculations. The heterogeneous geology of the subsurface of Hesse ranges from locally outcropping Paleozoic basement rocks to up to 3.8 km thick Cenozoic, porous sedimentary deposits in the tectonically active northern Upper Rhine Graben. The HIP was quantified for five sedimentary layers (Cenozoic, Muschelkalk, Buntsandstein, Zechstein, Rotliegend) as well as for the underlying basement. We present a set of maps allowing to identify geothermally prospective subregions of Hesse based on the laterally varying thermal energy stored within the units. HIP is predicted to be highest in the area of the northern Upper Rhine Graben in the Cenozoic unit with up to 700 GJ text {m}^{-2} and in the Rotliegend with up to 617 GJ text {m}^{-2}. The calculations account for the variable thicknesses and temperatures of the layers, density and heat capacity of the solid and fluid parts of the rocks as well as porosity.

No changes in overall AMOC strength in interglacial PMIP4 time slices

Abstract. The Atlantic Meridional Overturning Circulation (AMOC) is a key mechanism of poleward heat transport and an important part of the global climate system. How it responded to past changes in forcing, such as those experienced during Quaternary interglacials, is an intriguing and open question. Previous modelling studies suggest an enhanced AMOC in the mid-Holocene compared to the preindustrial period. In earlier simulations from the Palaeoclimate Modelling Intercomparison Project (PMIP), this arose from feedbacks between sea ice and AMOC changes, which were dependent on resolution. Here we present an initial analysis of recently available PMIP4 simulations for three experiments representing different interglacial conditions – one 127 000 years ago within the Last Interglacial (127 ka, called lig127k), one in the middle of the Holocene (midHolocene, 6 ka), and a preindustrial control simulation (piControl, 1850 CE). Both lig127k and midHolocene have altered orbital configurations compared to piControl. The ensemble mean of the PMIP4 models shows the strength of the AMOC does not markedly change between the midHolocene and piControl experiments or between the lig127k and piControl experiments. Therefore, it appears orbital forcing itself does not alter the overall AMOC. We further investigate the coherency of the forced response in AMOC across the two interglacials, along with the strength of the signal, using eight PMIP4 models which performed both interglacial experiments. Only two models show a stronger change with the stronger forcing, but those models disagree on the direction of the change. We propose that the strong signals in these two models are caused by a combination of forcing and the internal variability. After investigating the AMOC changes in the interglacials, we further explored the impact of AMOC on the climate system, especially on the changes in the simulated surface temperature and precipitation. After identifying the AMOC's fingerprint on the surface temperature and rainfall, we demonstrate that only a small percentage of the simulated surface climate changes could be attributed to the AMOC. Proxy records of sedimentary Pa/Th ratio during the two interglacial periods both show a similar AMOC strength compared to the preindustrial, which fits nicely with the simulated results. Although the overall AMOC strength shows minimal changes, future work is required to explore whether this occurs through compensating variations in the different components of AMOC (such as Iceland–Scotland overflow water). This line of evidence cautions against interpreting reconstructions of past interglacial climate as being driven by AMOC, outside of abrupt events.

Tuning heat transport via coherent structure manipulation: recent advances in thermal turbulence.

Tuning transport properties through the manipulation of elementary structures has achieved great success in many areas, such as condensed matter physics. However, the ability to manipulate coherent structures in turbulent flows is much less explored. This article reviews a recently discovered mechanism of tuning turbulent heat transport via coherent structure manipulation. We first show how this mechanism can be realized by applying simple geometrical confinement to a classical thermally driven turbulence, which leads to the condensation of elementary coherent structures and significant heat-transport enhancement, despite the resultant slower flow. Some potential applications of this new paradigm in passive heat management are also discussed. We then explain how the heat transport behaviors in seemingly different turbulence systems can be understood by this unified framework of coherent structure manipulation. Several future directions in this research area are also outlined.

Computational assesment of Carreau ternary hybrid nanofluid influenced by MHD flow for entropy generation

Tri-hybrid nano-particles in shear rate-dependent viscous fluid are essential for improving heat and mass transmission in many industries. The current study explores the two-dimensional flow of the Carreau-ternary hybrid nanoliquid with a magnetic field over the stretching surface. The heat transport mechanism is deliberated through the applications of thermal radiation and heat source/sink effects. The entropy minimization of the flow of Carreau ternary hybrid nanofluid has also been scrutinized. Further, the concepts of convective conditions are employed for the numerical solution of the existing model. In the present flow analysis, silver (Ag), Molybdenum disulfide (MoS2), and multi-wall carbon nanotube (MWCNT) nanoparticles are studied. Carboxymethyl cellulose (CMC-water) is used as a base liquid. The well-established numerical collocation finite difference scheme and three-stage Lobatto III as the built-in function of the bvp4c solver via MATLAB have been used to solve the system of equations in the form of concentration, energy, and momentum. Numerous features, such as flow speed, temperature, drag friction, and Nusselt number, are described in figures and tables. From the existing model, some key outcomes are that the rising values of the radiation parameter increased the heat transfer rates. Further, it is dissected that the greater importance of the magnetic field parameter declined the entropy generation and velocity of the liquid.

Entropy formation analysis for magnetized UCM fluid over an exponentially stretching surface with PST and PSHF wall conditions

<abstract> <p>This article aims to demonstrate the formation of entropy due to variable thermal conductivity, radiation, and fluid friction irreversibilities for a three-dimensional upper-convected Maxwell (UCM) fluid. The fluid motion occurs as a result of exponential stretching sheets. Separate discussions are held regarding the entropy generation related to the prescribed surface temperature and prescribed surface heat flux. Additionally, the heat transport mechanism is examined in the presence of thermal radiation. The governing physical situation is first modeled and then solved by using the homotopy analysis method to acquire the solution. The physical importance of relevant flow parameters is shown graphically and in tabular form. It is noted that the entropy generated is reduced with an increase in the thermal radiation parameter. Streamline patterns are also drawn for two- and three-dimensional UCM fluid models. Finally, the current analytical solution is found to be in agreement with the solutions in the literature.</p> </abstract>

FRACTAL ANALYSIS FOR THERMAL CONDUCTIVITY OF DUAL POROUS MEDIA EMBEDDED WITH ASYMMETRIC TREE-LIKE BIFURCATION NETWORKS

Heat transport in tree-like bifurcation networks has been widely studied in various fields. In this work, we investigate heat conduction in the dual porous media embedded with asymmetric tree-like bifurcation networks. In addition, considering the effects of nonuniform tube shape, we assume that the bifurcated tube shows sinusoidal fluctuations. Based on the fractal distribution of pore size and bifurcation structure, we established a dimensionless effective thermal conductivity (ETC) model of the dual porous media. The dimensionless ETC ([Formula: see text] obtained is related to the porosity ([Formula: see text], the fluid–solid thermal conductivity ratio ([Formula: see text], the pore area fractal dimension [Formula: see text] and the structural parameters of the bifurcation network (bifurcation level [Formula: see text], length ratio [Formula: see text], radius ratio [Formula: see text], fluctuation amplitude factor [Formula: see text], bifurcation angle [Formula: see text]. To verify the validity of this model, a comparison of the present dimensionless ETC model with available experimental data was carried out and the results were in good agreement. We have discussed the effects of each parameter on the dimensionless thermal conductivity in detail and constructed parametric planes to evaluate the structural parameters more directly. The model has positive implications for revealing the heat transport mechanism in asymmetric tree-like bifurcation dual porous media.

Dynamics of stratifications and magnetic dipole for radiative flow of ferromagnetic Sutterby fluid

AbstractThe purpose of current work is to explore the initial working of 2D ferrofluid flow passing over an elastic sheet with effects of magnetic dipole. Sutterby fluid model is under discussion along with ferrofluids which have been studied with focus on heat and mass transfer, including thermophoresis and Brownian motion effects. The particular flow design was preferred because of its common use in numerous fields such as biomedicine and engineering. In this paper, the effects of magnetic dipoles as well as thermal radiation for stretching surface in ferromagnetic fluids flow are deliberated. Moreover, the transport mechanism of heat and mass are accounted in view of stratifications and convective conditions. In this study we investigated the nonlinear Partial differential equations (PDEs) by use of some suitable similarity transformations; however, after that these Ordinary differential equations (ODEs) were analyzed numerically by using bvp4c approach. Results of viscous dissipation, Curie temperature and effects of thermal radiation on the velocity, temperature and concentration are also under consideration. Additionally, velocities, thermal gradients as well as mass transport rates are analyzed pictorially after that certain results are concluded. The major findings of this study depend on the consequence of control parameters on thermal field, momentum, and concentration. It is observed that the temperature of the magneto‐fluid increases for higher values of thermophoresis and Brownian motion interaction as well as Curie temperature parameters. The concentration distribution of ferrofluid represents an opposite trend for thermophoresis and Brownian motion.
