    Abstract: 固體火箭燃燒室中不穩定之燃燒是造成火 箭燃燒不穩定的主因.此研究計畫是利用長方 形管道及燃燒爐來模擬固體火箭推進劑火焰在 聲場影響下之不穩定燃燒現象,尤其是對溫度 及速度分布加以實驗探討,藉以了解產生燃燒 不穩定之條件及原理,以降低火箭任務之失敗. 首先將以99%純度甲烷及空氣混合氣之流速,當 量比以及聲波場頻率為參數,利用光電管系統 測量非穩態之火焰輻射,以及利用壓力轉換器 測量聲波場之動壓.所得之數據配合芮氏準則( Rayleigh criterion)之分析,將找出多組不同火焰趨 動或抑制聲波場特性之火焰結構及聲場頻率, 以作為進行溫度場及定性、定量速度場之量測並作分析比較.溫度之量測是利用非接觸性之 Rayleigh scattering及紅外線溫度量測;速度之量測 將由雷射測速儀(LDV)來執行.所得之穩態及非穩 態速度及溫度分布,將用以分析並歸納出火焰 結構與燃燒不穩定之相互關連,並探討燃燒不 穩定產生之條件及原理.
