| Abstract: | In the paper, the sloshing of liquid in a spherical tank is investigated under low-gravity conditions. After determination of the equilibrium shape of free surface of liquid, using a method concerning a kind of characteristic functions, expanded into po-lynominal expressions, the free and forced sloshing problem had been solved.The computer results for sloshing frequencies, dynamical coefficients and damping ratio had been obtained. |
