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.

Particle transport and heat loads in NIO1
Review of Scientific Instruments, 2015NIO1 is a compact radio frequency ion source designed to generate a 60 kV-135 mA hydrogen negative ion beam and it aims at continuous operation, which implies a detailed thermo-mechanical analysis of the beam-facing components, in particular, the accelerator grids. A 3D analysis of the entire NIO1 beam has been performed for the first time with a fully

It is known that heat transfer between two liquid-reservoirs maintained at different temperatures and connected to each other by a capillary bundle is markedly enhanced by oscillatory flow in the bundle. In this paper, first, the effects of physical properties of the working liquid on the enhanced heat flow rate are investigated.

In this chapter, we shall take a closer look at the transport of entropy. Simple aspects will be introduced that go beyond what we already studied in Chapter 4 (Section 4.6). This extends the treatment of thermal processes into the realm of phenomena which are missing from the theory of the thermodynamics of ideal fluids (Chapter 5).

Heat transportation by oscillatory flow in a new type of heat transportation pipe
International Journal of Heat and Mass Transfer, 2009Abstract The present paper deals with experimental and numerical study on the longitudinal heat transportation by an oscillatory water flow in a double tube type heat transportation pipe. Experiments were performed to measure the heat transportation rate in the ranges of 2.3 ⩽ Wo ⩽ 7.2 and 400 ⩽ Re max ⩽ 6600.

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.

Heat transport in serpentinites
Tectonophysics, 2003Abstract The thermal transport properties thermal conductivity and thermal diffusivity were examined for a variety of serpentinites as a function of temperature at ambient pressure. The thermal transport properties of serpentinites show an extraordinary behavior.
