The feasibility of using carbon foam as a heat sink and heat spreader in optoelectronic packages is assessed. A “supercooler” is designed, fabricated and tested to verify its cooling capability under high heat flux conditions in a typical optoelectronic package. The supercooler uses carbon foam as a primary heat transfer material. Water is soaked into the carbon foam and under evacuated pressur...

Additional experiments with the slowly varying axisymmetric hurricane model described by Anthes are presented. Variable horizontal eddy viscosity coefficients are utilized to study circulations that result from an increased heating function and a heating function with a double maximum along the radial direction. Infrared radiative cooling is modeled for the clear tropical atmosphere following S...

Temperature was measured in the left ventricle, aorta, liver, brain, lung, bone marrow, kidney, and spontaneous solid tumors in dogs undergoing whole body hyperthermia in a radiant heat device. Rectal temperature was found to be a satisfactory indicator of systemic arterial temperature during plateau temperature conditions but rectal temperature underestimated arterial temperature during heatin...

We apply wavelet-based time-localized phase coherence to investigate the relationship between blood flow and skin temperature, and between blood flow and instantaneous heart rate (IHR), during vasoconstriction and vasodilation provoked by local cooling or heating of the skin. A temperature-controlled metal plate (approximately 10 cm2) placed on the volar side of the left arm was used to provide...

an attempt was made to investigate the thermal and residual stress distribution in a novel three layer (la 2 zr 2 o 7 / 8ysz/ nicraly) during a real-like heating regime which includes heating, service time and final cooling. for achieving maximum accuracy and consistency in calculation of thermal and mechanical properties of hybrid coating system, all related andrequired properties were introdu...

In the recent attempts to stimulate alternative energy sources for heating and cooling of buildings, emphasis has been put on utilisation of the ambient energy from ground source and other renewable energy sources. Exploitation of renewable energy sources and particularly ground heat in buildings can significantly contribute towards reducing dependency on fossil fuels. This paper highlights the...

Over the past decades, Stockholm and Sweden have reduced CO2 emissions and increased resource efficiency, while maintaining high and sustainable economic growth. A major part of the recipe for success has been the development of the infrastructure for district heating and cooling. The district heating and cooling networks cover the Greater Stockholm Area. A set of large production plants, where...

The crystallization of ion beams has recently been established in the rf quadrupole storage ring PALLAS (PAul Laser CooLing Acceleration System) for laser-cooled 24Mg+ ion beams at an energy of about 1 eV. Yet, unexpectedly sharp constraints had to be met concerning the confinement strength and the longitudinal laser cooling rate. In this paper, related and up to now unseen heating mechanisms a...

This paper examines the effects of monotonic and cyclic temperature changes a model energy pile (diameter=25 mm, length=264 mm) on variations in volumetric water content surrounding unsaturated sand. Water flowed away from during heating to 36°C toward cooling 5°C, causing soil drying wetting near pile, respectively. The change was time-dependent, nonlinear, slower than continued evolve after s...
