Abstract利用失重飞机提供的短时失重、超重和常重力交变环境,研究了膜式静态水气分离器首级可视化分离室和再循环管道中的水气两相流动构型。首级分离室内变截面蛇形窄通道内变质量流率的气液两相流动表现为间歇状的、不稳定的溪状流,在不同重力阶段具有几乎相同的变化特征。再循环管路内的气液两相流主要以细碎的泡状流和弹状流为主,气泡或气团间平均间距极大,含气率演化过程具有强烈的间歇性,但在抛物线飞行过程中含气率变化的总体特征与重力水平的变化基本无关。这表明静态水气分离器的工作性能基本不受重力影响。
Other AbstractUtilizing the alternating environment of short-term reduced,super- and normal-gravity provided by a reduced gravity airplane,two-phase water-air flow patterns both in the first visible stage of a static membrane separator and in the recycled water line are studied experimentally in the present paper.Unsteady intermittent rivulet flow with variable mass flux is observed in the variable cross-section serpentine flow channel in the first visible stage,which exhibits the same characteristics in different gravity.Finely bubble flow and slug flow with mach large averaged space between air bubbles are observed in the recycled water line.Although much large fluctuation of void fraction is obvious in the recycled water line,the general characteristics is irrelative with the gravity.Thus,the performance of the separator is not dependent upon the gravity
