The paleoclassical model for radial electron heat transport in tokamak plasmas has been developed in a number of papers over the past few years. In order to facilitate numerical evaluation of it in plasma transport codes, this report summarizes its parameters, formulas and limits in particular regimes. A hierarchy of levels of the paleoclassical model are specified for interpretive (1) and pred...

Heat conduction [1] is usually modeled as a diffusion process embodied in heat conduction equation. The traditional numerical methods [2, 3] for heat conduction problems such as the finite difference or finite element are well developed. However, these methods are based on discretized mesh systems, thus they are inherently limited in the geometry treatment. This chapter describes the Monte Carl...

The meridional transport in the Pacific Ocean subtropical cell is studied for the period from 2004 to 2011 using gridded Argo temperature and salinity profiles and atmospheric reanalysis surface winds. The poleward Ekman and equatorward geostrophic branches of the subtropical cell exhibit an El Ni~ no–Southern Oscillation signature with strong meridional transport occurring during La Ni~ na and...

the present article focuses on the evaluation of a first-moment closure model applicable to film cooling flow and heat transfer computations. the present first-moment closure model consists of a higher level of turbulent heat flux modeling in which two additional transport equations for temperature variance kθ and its dissipation rate εθ are considered. it not only employs a time scale that is ...

9 Low enthalpy geothermal energy is a renewable resource that is still underexploited nowadays, in 10 relation to its potential for development in the society worldwide. Most of its applicabilities have 11 already been investigated, such as: heating and cooling of private and public buildings, roads defrost, 12 cooling of industrial processes, food drying systems, desalination. 13 One of the ma...

An underdeveloped class of oscillatory passive heat transport cycles are discussed that have the potential to transport significantly higher heat loads than current heat pipes. Prototype cycles employing inferior working fluids have demonstrated transport of higher heat loads over significantly greater distances than similarly sized heat pipes (including CPLs and LHPs) employing ammonia. Most o...

We study heat and charge transport through a normal diffusive wire coupled with a superconducting wire over the region smaller than the coherence length. Because of partial Andreev reflection of quasiparticles from the interface, the subgap thermal flow is essentially suppressed and approaches zero along with energy, which is specific for diffusive structures. Whereas the electric conductance s...
