Thermal cracking and endothermicity of China No. 3 aviation kerosene were studied experimentally under supercritical conditions relevant to regenerative cooling systems for scramjet applications. A multiple-stage heating system with reaction products collection was used that can achieve a fuel temperature ran...
Temperature variation can cause uneven expansion( contraction) of mineral particles and result in thermal cracking in the rock. Temperature mode exposed to rock can be divided into two types: heating and cooling.According to acoustic emission monitoring of thermally induced granite in the heating and...
athe test conditions may be only severe enough to produce varying degrees of cracking in the alloys of interest, in mechanical or thermal treatments used, or in sensitivity to specific environments investigated. 试验条件也许是只严厉的足够导致不同程度崩裂在合金利益,在机械或热量治疗用于,或者在敏感性被...
–Drying shrinkage and thermal cracking of the harden concrete. In addition to high concrete temperature, hot weather concreting is greatly affected by the ambient condition such as low humidity, wind, and high environment temperatures. It is always important to have a good plan, monitor the concr...
Understanding coal permeability as impacted by thermal damage is crucial to the detection of coal and gas hazards in deep coal mining. In this study, tri-axial compression experiments were performed to examine the damage and the permeability evolution process of methane-containing coal under different...
11.Effects of catalytic cracking conditions on biomass tar cracking催化裂化条件对处理生物质热解焦油的影响 12.The boiling heat transfer theory are employed to treat the nonlinaer boundary conditions.计算中利用沸腾传热理论处理了非线性边界条件。 13.The thermal processes required in these situations, as ...
In a tightly wound superconducting magnet such as a resin-impregnated or a nonimpregnated magnet, conductor motion within the winding or cracking of epoxy resin often causes a quench of the magnet. Based on an experimental result and theoretical analysis of conductor motion, their time constants ...
Likewise, these observations offer only a snapshot of the current epoch and a limited inference of the historical state of ground ice. Polygonal patterned ground formed by thermal-contraction cracking of ice-cemented permafrost may offer insight to the current or past occurrence of ground ice (e....
aTo compare materials or environments for relative stress-corrosion behavior, the test conditions may be only severe enough to produce varying degrees of cracking in the alloys of interest, in mechanical or thermal treatments used, or in sensitivity to specific environments investigated. 要比较材料或环...
