    摘要:

    利用Helmholtz型脈動燃燒器，進行了不同燃?xì)饬髁織l件下的脈動燃燒運行實驗，在3組不同尾管長度條件下，運行頻率都隨燃?xì)饬髁康脑龃蠖龃?。探究了燃?xì)饬髁繉γ}動燃燒頻率的影響，根據(jù)理論值與實測值的差異，提出Helmholtz型脈動燃燒器頻率計算的修正公式，并對修正后的公式進行檢驗，實驗值與理論值吻合度較好。

    Abstract:

    In order to further understand the frequency of Helmholtz pulse combustor, a Helmholtz type combustor was used to carry out the experiments in conditions of different gas flow rates. Through the experiments of three lengths tail pipe, frequency was all increased while the gas flow rate increased. The impact of gas flow rate on frequency was investigated, and the modification of theoretic formula was also proposed based on the difference between the theoretical and actual values. Compared with the experimental values, the results showed that the predicted values and the experimental values matched well.
