碳氫化合物燃燒的負温係數效應
Negative Temperature coefficient Effect in the Combustion of Gaseous Hydrocarbon
摘要
碳氫化合物燃燒現象中，以冷焰振盪、二段點火及負溫係數效應最爲顯著。早期的燃燒化學家已發现冷焰振盪和負溫係數效應間有著密不可分之關係存在。本文將以Yang Gray模型及作者推測之三變數的注牟熱動力模型及乙醛氧化化學模型，經由數值計算能量産生率並配合碳氫化合物燃燒之實驗觀察，深入探討燃燒動力行爲和負溫係數間之相關性；並對一般碳氫化合物燃燒提出它們之負溫係數效應發生之一般原因及理論。

There are close relationship between negative temperature coefficient effect and the existence of cool name oscillations in the combustion of gaseous hydrocarbon. we analyzed the three variable thermokinetie model devised by Wang and Mao for the case of acctaldehyde combustion. We find in this model various dynamical behaviors that are associated with negative temperature coefficient effect. Then we investigated the average power output of this model by numerical simulation. Finally, general features of this phenomenon are discussed.
