| Abstract for Research Report | The transition mechanism during the combustion process, leading to critical events such as extinction, ignition, flaming, and explosions, is crucial from a fire safety perspective. Recently, for example, lithium-ion (Li-ion) batteries have been widely used in various electric devices, leading to significant accidents due to the weak thermal stability of the energetic materials, causing significant losses and impacting the company’s reputation. Another example is the transition to flaming, prevalent in many biomass fuels and one of the leading causes of Wildland fires. These critical events share similar causes that can be explained by energy balance concepts. The critical threshold can be triggered if heat generation overcomes heat loss. Therefore, this study aims to understand and prevent these critical events in combustion processes experimentally and theoretically. Experts in mathematics and combustion/safety engineering will participate in a short-term joint project. The experimental investigation into the thermal behavior of Li-ion batteries will be conducted by a team member, and the theoretical model will be validated based on the experimental data. Moreover, discussions on other related critical events will also be conducted to develop new models and identify mutual features among these events. |
