Heating Capacity

the paper determines and calculates variation of gas and heating capacity in a combustible organic rock, the experiment shows that organic sample radiating intensity is low when temperature is below 110 °C, it gradually increased more than 110 °C when the heat release rate increases considerably. the speed of CO and CO2production rates increased slowly nevertheless the temperature is up to 65°C and raised faster and finally enhanced dramatically. Organic rock combustion can be inhibited effectively by lowering the temperature and reduce Organic Rock oxidation velocity.

A series of experiments was designed to investigate the effects of ceiling on upward flame spread. The result reveals that the ceiling accelerates the burning rate of upward flame under certain situations. And the acceleration is slightly increase with the increasing sample length, but almost keeps the same with different sample width. The heat release rate per unit area nearly keeps the same for the series work with ceiling or the series work without ceiling. But the heat release rate per unit area between the two series is obvious, the heat release rate per unit area with ceiling is much higher than the ones without ceiling.

In this study, to allow the flashover to occur, combustion tests were conducted by setting the conditions of a fire source using a large-scale compartment and changing the opening condition. As a result, the inside temperature of the compartment was measured under the fire source conditions. Moreover, according to the “Handbook on Design Calculation &#x0004d;ethods of Fire Behavior” by the Architectural Institute of Japan, the validity of the heat release rate required for the flashover to occur was verified through the correlation between <math xmlns="http://www.w3.org/1998/Math/MathML"><msub><mi>Q</mi><mrow><mi>F</mi><mi>O</mi></mrow></msub><mo>/</mo><msub><mi>Q</mi><mrow><mi>v</mi><mi>m</mi><mi>a</mi><mi>x</mi></mrow></msub></math> and <math xmlns="http://www.w3.org/1998/Math/MathML"><msub><mi>A</mi><mi>T</mi></msub><msup><mrow><mo>(</mo><mi>k</mi><mi>p</mi><mi>c</mi><mo>)</mo></mrow><mrow><mn>1</mn><mo>/</mo><mn>2</mn></mrow></msup><mo>/</mo><msub><mi>c</mi><mrow><mi>P</mi></mrow></msub><mn>0</mn><mo>.</mo><mn>5</mn><mi>A</mi><msup><mi>H</mi><mrow><mn>1</mn><mo>/</mo><mn>2</mn></mrow></msup></math>.

In the current study, through a set of nail penetration and impact tests on modified lithium-ion battery coin half-cells, we examine the effects of electrode pattern on the heat generation behaviors associated with internal shorting. The results show that the temperature profile is quite insensitive to the openings in cathode layer, which may be attributed to the high specific energy as well as the secondary conductive paths. This finding will considerably influence the study in the area of thermal runaway mitigation of energy storage systems.
