  • cavity : n. 1. 【解剖學】穴,窩,盂,腔,空腔;【醫學】(空)洞。2. 【物理學】模槽;氣蝕區;空腔諧振器;【原子能】(反應堆中的)小室,暗盒。
  1. The simulations results show that the spoiler is available to make the fuel and the oxidizer coming from the former to stay in the cavity for a long time, to let the fuel and oxidizer mix and burn completely. since there is a high temperature zone forming by vortex in the middle of the motor, it required a restricted thermal protection. the plate with holes decreased the vortex function in the cavity, which could not promote the combustion efficiency, but to decrease temperature in the cavity and be benefit to thermal protection of the wall

    計算結果分析表明:擾流板可以使燃料和氧化劑在擾流腔內的滯留時間加長,促進燃料與氧化劑的摻混燃燒,提高燃燒效率,但由於渦流在發動機的中間部位形成了高溫燃燒區域,致使局部燃料和絕熱層燒蝕速率增大,加大了熱防護的難度;孔板結構減弱了擾流腔內迴流區的漩流作用,不能增加推進劑燃燒效率,但可以使擾流腔內的溫度降低,給壁面熱防護帶來好處。
