Equivalent Dynamic of Liquid Sloshing Coupled with Mass Transfer During On-Orbit Refueling

What is it about?

During the on-orbit refueling mission, the liquid fuel partially filling in the tanks will slosh and produce coupling motion with servicer-to-client mass transfer, which will affect the stability of attitude motion of the combined spacecraft. In this paper, we establish a practical modeling method to predict the sloshing and transfer coupled motions of the liquid fuel in cylindrical tanks during refueling, and the proposed method is testified by professional calculation fluid dynamics (CFD) software.
