The design of a wall, as insulating as possible with respect to heat transfer, is discussed. Several materials are considered and evaluated with respect to conduction, convection and radiation, which are the three heat transfer modes.doi:10.1088/0143-0807/26/1/002J L Brun...
In fast breeder reactors (FBRs), hydrogen, one of the major impurities in sodium coolant, is used for water leak detection and tritium control in the interest of operating nuclear plant safety. It is essential to evaluate the hydrogen flux into the sodium coolant through the heat transfer ...
It is found that for good thermal conductors, the corrections are small (within a few percent), while for poor thermal conductors the corrections may be substantial (30% for a wall with conductivity similar to brick). In addition, expressions for the heat transfer coefficient h as well as ...
For instance, Saidi and Kim [15] proposed a heat flux sensor that measures both heat transfer and temperature with minimal effect on the wall’s thermal boundary condition since the passive temperature sensor is very thin. Cucumo et al. [16] studied the degree to which the heat flux of ...
Porsche fans world wide will be celebrating this years Le Mans 24 one -two victory, as well as the manufacturers overall Le Mans 24 victory tally being increased by one to a total of 17. And with Porsches upcoming Rennsport Reunion V , with a “Legends of Le Mans” theme, September in...
aThe temperature of the fluid in compressible flow through a conduit of constant cross section may be kept constant by a transfer of heat through the conduit walL Long, small, uninsulated pipes in contact with air transmit sufficient heat to keep the flow nearly isothermal. Also, for small ...
To reduce the possibility of heat-related injuries or of overheating the device, do not place the device directly on your lap or obstruct the device air vents. Use the device only on a hard, flat surface. Do not allow another hard surface, such as an adjoining optional printer, or a ...
1) heat transfer through the wall 墙体传热1. In addition heat transfer through the wall and solar radiation play a very important role in temperature field and heat eliminated by the natural ventilation. 本文针对建筑内部热源及羽流,建筑墙体传热和太阳辐射作用对通风效果的影响进行实验研究。
1983: VISIONARIESWhen Liberty Sport introduced Rec Specs in 1978, the eyewear manufacturer had no idea it would start a love affair between fans and players in goofy goggles. Future Hall of Fame running back Eric Dickerson, who picked up a pair as a rookie with the LA Rams in 1983, was ...
In the NRCC experiment [30], four heat flow transducers were used to measure and record the total heat flux on the external wall. These were mounted at 1.0 m vertical intervals with the lowest at 0.5 m above the centre of the opening’s top edge. This arrangement of heat flux measurement...
