【摘要】：首先分析討論了油氣爆炸過程中火焰燃燒模式的估計方法,然后在激波管內(nèi)進(jìn)行了低、中、高3次不同初始油氣濃度條件下的油氣爆炸實驗,通過實驗數(shù)據(jù)分別計算出了低、中、高初始油氣濃度條件下油氣爆炸在初期、中期和后期的丹姆克爾數(shù)和湍流雷諾數(shù),最后依靠丹姆克爾數(shù)-湍流雷諾數(shù)圖對低、中、高初始油氣濃度條件下油氣爆炸初期、中期和后期的火焰燃燒模式進(jìn)行了定量估計。結(jié)果表明:低、中、高初始油氣濃度條件下激波管油氣爆炸過程初期、中期和后期的火焰燃燒模式均為漩渦內(nèi)小火焰模式。
[Abstract]:Firstly, the estimation method of flame combustion mode in the process of oil and gas explosion is analyzed and discussed, and then the oil and gas explosion experiments are carried out in the shock tube under the conditions of low, middle and high initial oil and gas concentrations for three times, and the low values are calculated by the experimental data, respectively. Under the condition of high initial oil and gas concentration, the Damkel number and turbulent Reynolds number in the initial, middle and late stages of oil and gas explosion, and finally depend on the low, middle and high initial oil and gas concentrations in the low, middle and high initial oil and gas concentration conditions, and finally depend on the low, middle and high initial oil and gas concentrations. The mid-and late flame combustion modes were quantitatively estimated. The results show that at low, medium and high initial oil and gas concentrations, the flame combustion modes in the initial, middle and late stages of shock tube oil and gas explosion are both small flame models in swirl.
