Non-Hermitian Chiral Heat Transport
Physical Review Letters, 2023Exceptional point (EP) has been captivated as a concept of interpreting eigenvalue degeneracy and eigenstate exchange in non-Hermitian physics. The chirality in the vicinity of EP is intrinsically preserved and usually immune to external bias or perturbation, resulting in the robustness of asymmetric backscattering and directional emission in classical

Increasing heat may impede peoples’ ability to be active outdoors thus limiting active transport options. Co-benefits from mitigation of and adaptation to global warming should not be assumed but need to be actively designed into strategies.

Heat Transport without Heating?
2020When the spatial dimensions of metallic heterostructures shrink below the mean free path of its conduction electrons, the transport of electrons and hence the transport of thermal energy by electrons continuously changes from diffusive to ballistic.

Abstract The ability to ascertain the implications of a changing climate are based first and foremost on our understanding the fundamental balances comprising earth’s climate. The global energy budget is integral to this understanding, and the poleward transport of heat by the oceans is an intrinsic component of the energy balance.

The Physics of Fluids, 1960
The character of heat transport by cellular convection, which arises beyond the marginal state of stability in a layer of fluid bound between two constant temperature surfaces is examined. It is shown that a simple equation characterizes the heat transport in the neighborhood of the marginal state of stability when the convection is steady, and its ...

As mentioned in Chapter 1 the equations governing heat transfer with small temperature differences also govern transfer of small concentrations of other passive scalar contaminants. Particle-laden flows (Chapter 7) are excluded unless the particles are so small that they move with the flow and are negligibly affected by gravity.

After the theory lectures touching aspects of continuum mechanics of porous media, thermodynamics and an introduction of numerical methods, now we conduct five exercises on heat transport simulation using OGS—so called TH (thermo-hydraulic) processes.

Poleward heat transport by the atmospheric heat engine
Nature, 2002The atmospheric heat transport on Earth from the Equator to the poles is largely carried out by the mid-latitude storms. However, there is no satisfactory theory to describe this fundamental feature of the Earth's climate. Previous studies have characterized the poleward heat transport as a diffusion by eddies of specified horizontal length and ...

Decoupling charge and heat transport
Science, 2017Solid-State Physics In metals, electrons carry both charge and heat. As a consequence, electrical conductivity and the electronic contribution to the thermal conductivity are typically proportional to each other. Lee et al.

In Sect. 3.2 we saw that when a hot (or cold) fluid flows past a cold (or hot) body of size L, with a characteristic velocity U such that the Peclet number is large, i.e., \(Pe = UL/\alpha \gg 1\), then the convective heat flux is in general much larger than is diffusive counterpart.
