• 中文摘要： 火箭燃料在微重力下可能形成不同的不穩定性。本文研討在微重力下火箭燃料之動態及其流體之處理。本研究主要使用超級計算機CRAY X-MP之數字模擬計算。有些計算結果與無重力自由落體飛機KC-135之實驗對照，驗核一致符合。
• 英文摘要： The instability of liquid and gas interface can be induced by the presence of longitudinal and lateral accelerations, vehicle vibration, and rotational fields of spacecraft in a microgravity environment. In a spacecraft design, the requirements of settled propellent are different for tank pressurization, engine restart, venting, or propellent transfer. In this paper, the dynamical behavior of liquid propellent, fluid reorientation, and propellent resettling have been carried out through the execution of a CRAY X-MP super computer to simulate fluid management in a microgravity environment. Characteristics of slosh waves excited by the restoring force field of gravity jitters have also been investigated.
