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 of transport and heat capacity of transport of some aqueous electrolytes
Canadian Journal of Chemistry, 1988The thermal diffusion of aqueous solutions of NaCl, KCl, MgCl2, BaCl2, MgSO4, and CuSO4 (0.05 m) contained in the pores of a sintered glass diaphragm has been studied. A cell is designed and fabricated for this purpose, and the resulting heat of transport values are compared with those available from the literature and obtained by using independent ...

Acoustically enhanced heat transport
Review of Scientific Instruments, 2016We investigate the enhancement of heat transfer in the nucleate boiling regime by inducing high frequency acoustic waves (f ∼ 106 Hz) on the heated surface. In the experiments, liquid droplets (deionized water) are dispensed directly onto a heated, vibrating substrate.

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.

Heat of transport of air in clay
Radiation Protection Dosimetry, 2006By measuring the thermomolecular pressure difference and using principles of irreversible thermodynamics, heat of transport of air in clay and its coefficient of diffusion are found. A comparison of thermotranspiration and pressure driven gas fluxes through concrete slab in homes is examined.

Impact of Nanoscale Roughness on Heat Transport across the Solid–Solid Interface
Advanced Materials Interfaces, 2019The performance of 1D nano/microbeam‐based devices greatly relies on heat dissipation to substrates. The surface roughness plays a key role in interfacial heat transport while this issue is seldom investigated due to the difficulty in quantitative ...

Estimating Heat-Transport and Time-Delays in a Heat Exchanger
2018 IEEE Conference on Control Technology and Applications (CCTA), 2018Transport and heat exchange phenomena occuring in a heat exchanger can be modeled as first-order hyperbolic partial differential equations (PDEs). Reformulating these equations as a time-delay system preserves the infinite-dimensional property of the system, yet decreases its mathematical complexity.

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

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.
