temperature gradient At sea, a temperature gradient is the change of temperature with depth; a positive gradient is a temperature increase with an increase in depth, and a negative gradient is a temperature decrease with an increase in depth. ...
Moreover, it was found that the temperature gradient has little effect on the cracking mode of the TBCs because the stress distribution characteristics in TBCs subjected to thermal cycling with different temperature gradients remain unchanged based on the numerical simulation results....
A Temperature-Gradient-Induced Failure Mechanism in Metallization Under Fast Thermal Cycling 来自 掌桥科研 喜欢 0 阅读量: 57 作者:T Smorodin,J Wilde,P Alpern,M Stecher 摘要: In this paper, a novel mechanism is shown to cause the failure evolution in a metallization system under fast ...
One group quantitatively investigated the influence of the temperature gradient on the thermal cycling performance of a micro-tubular SOFC [100]. In their study, they combusted exhaust hydrogen at the fuel outlet to artificially create an axial temperature gradient in the tubular SOFC. The SOFC ...

The thermodynamic properties of frozen soil depend on its temperature state and ice content. Additionally, the permeability coefficient significantly affects both the temperature distribution and water movement. In this study, the dynamic variation of so
Resistance to this kind of attack becomes more important at higher temperatures, when the melting temperature of the CMAS deposits is exceeded and a penetration into the coating microstructural features (cracks and pores) can take place. During cooling the CMAS solidifies and the coating loses its...
For this study, a novel laboratory test technique and apparatus was developed to simulate low temperature cycling (-6.7, -12.2, -17.8 and -23°C) encountered in Pentane/LPG storage steel spheres. The ΔT between the cooled inner surface and the insulated outer surface of steel panels was ...
The inset shows the cryogenic thermal cycling procedure from a high temperature (323 K) to liquid nitrogen temperature (77 K), together with the waiting time, t, at both the maximum and the minimum temperatures. c Variation of average hardness value along the distance from the center. ...
(notably temperature), though with obvious limitations that must also be considered (Körner, 2007). Altitude has often been used as a proxy for latitude, allowing the study of biogeographical processes that occur at the scale of the planet over a short vertical gradient (Körner, 2000). ...
