“…Much room is left for the many-body radiative heat transfer theory. The many-body radiative heat transfer theory considering the interactions with infinite planar geometries needs to be developed, which will be useful to study the NFRHT for nanoparticles placed in nanochannels [80,81]. To go beyond the dipole approximation, the many-body radiative heat transfer theory should include higher electric and magnetic multipoles for smaller separation distances and consider multiple larger finite sized objects.…”

The many-body radiative heat transfer theory [P. Ben-Abdallah, S.-A. Biehs, and K. Joulain, Phys.Rev. Lett. 107, 114301 (2011)] only considered the contribution from the electric dipole moment. For metal particles, however, the magnetic dipole moment due to eddy current plays an important role, which can further couple with the electric dipole moment to introduce crossed terms. In this work, we develop coupled electric and magnetic dipole (CEMD) approach for the radiative heat transfer in a collection of objects in mutual interaction. Due to the coupled electric and magnetic interactions, four terms, namely the electric-electric, the electric-magnetic, the magnetic-electric and the magnetic-magnetic terms, contribute to the radiative heat flux and the local energy density. The CEMD is applied to study the radiative heat transfer between various dimers of nanoparticles. It is found that each of the four terms can dominate the radiative heat transfer depending on the position and composition of particles.Moreover, near-field many-body interactions are studied by CEMD considering both dielectric and metallic nanoparticles. The near-field radiative heat flux and local energy density can be greatly increased when the particles are in coupled resonances. Surface plasmon polariton and surface phonon polariton can be coupled to enhance the radiative heat flux.

“…Properties of nanofluids, such as thermal conductivity and viscosity, are complex functions of many different parameters, including temperature, particle size, and particle aggregation. Expensive experiments [113][114][115] and time-costly simulations [116][117][118][119][120] have attempted to delineate this complex behavior with little success.…”

The re-kindled fascination in machine learning (ML), observed over the last few decades, has also percolated into natural sciences and engineering. ML algorithms are now used in scientific computing, as well as in data-mining and processing. In this paper, we provide a review of the state-of-the-art in ML for computational science and engineering. We discuss ways of using ML to speed up or improve the quality of simulation techniques such as computational fluid dynamics, molecular dynamics, and structural analysis. We explore the ability of ML to produce computationally efficient surrogate models of physical applications that circumvent the need for the more expensive simulation techniques entirely. We also discuss how ML can be used to process large amounts of data, using as examples many different scientific fields, such as engineering, medicine, astronomy and computing. Finally, we review how ML has been used to create more realistic and responsive virtual reality applications.

“…However, in nanoconfined liquids, it is found that the near interface layering generates a structured arrangement of molecules leading to the predominance of vibrational transport. 32,33 The vibrational modes of transient energy can also exist as librational modes propagating through the strong van der Waals and coulombic force fields or phonon-like modes propagating through the hydrogen bond network. 34 Both have a longer range of propagation compared to the normal modes in bulk liquids.…”
