Abstract:

Propellant slosh in launch vehicles has been a major concern since the development of liquid propellant fuelled rockets. Unless sloshing in propellant tanks is controlled, it might cause vibrations of large amplitude which would result in instability of flight. This study presents a new method to model fuel sloshing in propellant tanks and extracts the fundamental slosh frequency. Computational Fluid Dynamics software, STAR CCM+ is used for the study. Volume of Fluid Model is used for modeling the fluid. The slosh frequencies of two cylindrical tanks of different dimensions are considered for the slosh studies. The proposed procedure is validated by comparing the slosh frequencies obtained using the software with those obtained using a closed form solution.
