With the progress of human activities in space, the occasion to handle liquids under low-gravity conditions is now growing. The absence or diminution of gravity force makes it difficult to position and control the liquid in a desirable manner. For the establishment of the technology for the management of liquid propellant in space vehicles, a numerical method, called 'CIP-LSM' (CIP Level Set method & MARS), was developed to simulate three-dimensional free-surface flows under various gravity conditions, which has been applied to clarify the dynamic behavior of liquid propellant in the tanks of launch vehicles.
