The Computational Fluid Dynamics (CFD) method, which is widely used by many researchers [2,3], has been proved to be an effective approach to reveal the sloshing motion, especially in case of low-gravity and zero-gravity liquid sloshing.
However, due to the high complexity of spacecraft systems and the limitations of the onboard computers on the CPU speeds and memory sizes, the CFD simulations are not available.
Baeten[13-15] adopted a three-dimensional time accurate particle-cluster method to prediction the spacecraft fuel sloshing in experimental satellite, the simulation results showed that sloshing effects and impact forces was close to those obtained from the experimental satellite.
