With the progress of human activities in space, the occasion to handle liquids under low gravity conditions is now growing. On the launch vehicles with liquid propulsion system, the dynamic acceleration during its powered ascent or ballistic flight makes it very difficult to control the position of propellants in the tanks. To establish the technology for the “propellant management” (2-3), it is essential to accumulate technical knowledge and experiences for the appropriate assessment of the fluid systems. However, in the atmosphere, there are not so many opportunities to realize the low-gravity state or the dynamic conditions of acceleration with airplanes or drop towers. Investigative methods based on Computational Fluid Dynamics, CFD, are therefore strongly desired.
