“…[179], Lee et al [180,181] devised a novel interfacial boundary collision rule for the simulation of multiphase phonon hydrodynamics to tackle the heat transport between dissimilar materials. In spite of these pioneering work, the lattice Boltzmann modeling is still in its fancy due to the following aspects: (1) dimensionless variables are taken in all of these simulations [158,[179][180][181] There are several other reports [58,79,80,[182][183][184] on lattice Boltzmann modeling of phonon transport in both bulk and nanostructured materials in the last several years. They are not introduced here because from a point of view of the classical phonon hydrodynamics where the N process dominates the phonon transport, their schemes of lattice Boltzmann model deal with only the R process, which beyond the classical phonon hydrodynamics.…”

Since SF 6 has high liquefaction temperature, the reliability of GIS, GIL and other gas insulated electrical equipment is reduced, and the maintenance cost is high in areas with high latitude. Therefore, applying mixed gas of SF 6 and N 2 as an insulating medium can reduce the liquefaction temperature of the medium under the precondition of maintaining certain insulation strength. In the paper, a breakdown experimental platform was built to study the insulating property of SF 6 /N 2 at low temperature. A slightly non-uniform electric field was generated by a hemisphereplate electrode. The breakdown voltage of SF 6 /N 2 with different mixing proportions at different gas pressures under low temperature condition was measured, therefore the influence law of temperature on mixed gas breakdown voltage was analyzed. The result showed that the insulating property of unliquefied mixed gas was not affected by temperature greatly in the slightly nonuniform electric field. The result in the paper has certain reference significance for applying SF 6 /N 2 in GIS and other electrical equipment of high latitude areas.
