【摘要】：開展了聯(lián)焰板長度對駐渦燃燒室凹腔冷態(tài)流場特性影響的數(shù)值研究,結(jié)果表明:聯(lián)焰板的流向長度存在兩個臨界值:Lc1=1mm和Lc2=9mm,當(dāng)聯(lián)焰板的流向長度小于等于臨界長度Lc1時,主流會卷入凹腔中,凹腔中無法形成雙渦結(jié)構(gòu);當(dāng)聯(lián)焰板的流向長度大于臨界長度Lc1小于等于Lc2時,凹腔中可以形成雙渦結(jié)構(gòu),但仍有部分主流會卷入凹腔中;當(dāng)聯(lián)焰板流向長度大于Lc2時,凹腔中可以形成雙渦結(jié)構(gòu),主流幾乎不會卷入凹腔中。
[Abstract]:The numerical study of the effect of the length of the flame coupling plate on the cold flow field characteristics of the cavity in the standing vortex combustor is carried out. The results show that there are two critical values: 1 mm and 9 mm in the flow direction of the flame coupling plate. When the flow direction length of the flame coupling plate is less than or equal to the critical length Lc1, When the flow length of the flame coupling plate is larger than the critical length Lc1 is less than equal to equal to Lc2, the double vortex structure can be formed in the cavity, but some of the mainstream will be involved in the cavity. When the flow length of the flame coupling plate is larger than Lc2, the double vortex structure can be formed in the cavity, and the mainstream will hardly get involved in the cavity.
