摘要:	此研究是實驗探討有關管道中側向預混火焰所激發之壓力振盪。研究結果顯示,火焰趨動之壓力振盪僅產生在火焰非常接近爐面及某些燃料當量比;在富油之情形下,並無壓力振盪發生。這些激發之壓力振盪頻率和當量比有關,且隨著當量比減少而降低,同時,有"beats"之現象產生。在大部分之實驗中,這些激發壓力振盪之主頻率與管道之自然頻率非常接近。 This paper describes results of an experimental study of sound wave generation by a premixed flame stabilized on the sidewall of a long rectangular duct. This flame-driven oscillations were investigated at different equivalence ratios. These studies reveal that pressure oscillations were observed only with the flame stabilized very close to the burner surface and only at certain equivalence ratios. No oscillation was observed in the fuel rich side. In addition, the frequencies of these excited pressure oscillations depend upon the equivalence ratios, and in most tests, "beats " were observed. The main excited frequencies decrease as the equivalence ratios decrease, and, however, most of them are close to the harmonics of the experimental tube.
