Nanofluids, stabilized suspensions of nanoparticles typically < 100 nm in conventional fluids, are evolving as potential enhanced heat transfer fluids due to their better thermal conductivity, increase in single phase heat transfer coefficient and significant increase in critical boiling heat flux. In the present paper, we investigate the overall thermal resistance of a closed two-phase thermos...

Air-breathing, diving ectotherms are a crucial component of the biodiversity and functioning of aquatic ecosystems, but these organisms may be particularly vulnerable to the effects of climate change on submergence times. Ectothermic dive capacity is thermally sensitive, with dive durations significantly reduced by acute increases in water temperature; it is unclear whether diving performance c...

Using time-domain thermoreflectance, we have measured the transport of thermally excited vibrational energy across planar interfaces between water and solids that have been chemically functionalized with a self-assembled monolayer (SAM). The Kapitza length--i.e., the thermal conductivity of water divided by the thermal conductance per unit area of the interface--is analogous to the "slip length...

Electric arc stabilized by a vortex of liquid, mostly water, is used in a special type of plasma torch for generation of thermal plasma jet with extreme plasma parameters. The paper presents analysis of properties and processes of water stabilized arcs and discusses differences from common gas stabilized arcs. Plasma torch utilizing stabilization of arc column by combination of gas flow and liq...

The curative use of thermal spring water is well known, but further investigation of its biological properties and therapeutic benefits is necessary. This present article reports all available scientific data concerning La Roche-Posay Thermal Spring Water and provides a better understanding of the biological mechanism of action of this water in regard to its composition and physicochemical prop...

in this article cuo/water nanofluid was synthesized by using polyvinylpyrolidone (pvp) as the dispersant.  thenanofluid stability period and the heat transfer enhancement were determinedby measuring the thermal conductivities. to study the nano-fluid stability, zeta (ζ) potential, and absorbency were measured under different ph values and pvp surfactant concentrations; also thermal conductivity...

the climatic, geographic and topographic characteristics, ecological conditions, forest and pastures, strong water resources, high vegetation, wild life and various hunting areas of kurdistan province are strong tourist centers. in this research using gis potential of suitable zones for claiming, rocking, ranging, visiting the nature, thermal spring, ski and winter sport, water sports and fishi...

The thermal diffusion behavior of acetone/water and dimethylsulfoxide(DMSO)/water mixtures has been experimentally investigated by a transient holographic grating technique named thermal diffusion forced Rayleigh scattering (TDFRS). For both systems a sign change of the Soret coefficient S(T) with varying water content has been predicted by simulations [C. Nieto Draghi et al., J. Chem. Phys. 12...

INTRODUCTION Prehospital maritime transportation in northern areas sets high demands on hypothermia prevention. To prevent body cooling and hypothermia of seriously-ill or injured casualties during transportation, casualty coverings must provide adequate thermal insulation and protection against cold, wind, moisture, and water splashes. OBJECTIVE The aim of this study was to determine the the...
