Due to this, such desirable absorption/emission properties that the heat-absorbing material absorbs sunlight in the visible light region and reflects sunlight in the infrared light region can be obtained. The cermet can retain high heat resistance because the film formation necessitates no complicated...
The heat of vaporization of a substance is the change in specific enthalpy at 1 atm and the normal boiling point when transitioning between: (Choose the best choice) a) Vapor and liquid b) Solid and liquid c) Vapor and solid What is the process that happens...
It has been widely recognized that the combustor or air reactor should be operated in a fluidized bed mode for better heat and mass transfer, and the associated reactions are intrinsically fast and are thermodynamically favored. However, unlike the oxidation reaction in the combustor, the reactions...
type adsorbent composition for canisters that can effectively prevent changing in temperature due to the heat of absorption/desorption and has a high butane working capacity; a process for producing the adsorbent; and a canister employing the latent-heat storage type adsorbent composition for canisters...
and as the material cures, it absorbs heat, thus there is a negative volumetric heat source that is a function of , the heat of the reaction. The rate of change of the degree of cure is often described by: (2) where the Arrhenius equation defines the temperature-dependent reaction rate,...
Solar Heat Responsive Exterior Surface Covering An exterior surface covering has a colored outer layer that transmits infrared radiation and an inner layer with a thermochromic pigment that absorbs heat ... HM Kalkanoglu,ML Shiao,KC Hong,... 被引量: 0发表: 2008年 Bioconversion of fruit peels,...
Laser ablation occurs only when the substrate material strongly absorbs the wavelength of the transmitted radiation. Hence, surface finishing, surface coating, and thermal conductivity are parameters which will lead to more or less effective laser milling. The process parameters that can be controlled ...
Hot-water heat exchanger absorbs heat equal to that coming together with hot gases downstream of engine heat exchanger. Heat pump operates under constant conditions at its maximum efficiency: . EFFECT: improved efficiency due to utilization of solar heat dissipated through atmosphere. 展开 ...
higher efficiency of heat transfer. The presence of the fine coke in the agglomerate allows decreasing consumption of this expensive coke, 3-4" in size, and also helps improve the melting process and minimizes the reduction of CO2to CO, which process absorbs heat and creates additional pollution...
fuel vapor (hereinafter sometimes referred to as simply an "adsorbent") and a powdery heat-storage material comprising a microencapsulated material that absorbs or releases latent heat in response to temperature change and undergoes phase changes (Hereinafter referred to as a "phase-change material")...
