The dynamic behaviour of fluids affected by asymmetric gravity jitter oscillations, in particular the effect of surface tension on partially-filled rotating fluids in a dewar tank, with and without installing baffle-board, imposed by time-dependent directions of background gravity have been investigated. Results show that lower frequency gravity jitter imposed on the time-dependent variations of the direction of background gravity induced a greater amplitude of oscillations and a stronger degree of asymmetry in liquid–vapour interface geometry than that made by the higher frequency gravity jitter. As the viscous force, between liquid and solid interface, greatly contributes to the damping effect of slosh wave excitation, a rotating dewar installed with baffles provides more area of liquid-solid interface than a rotating dewar without baffles. Results show that the damping effect provided by the baffles reduce the amplitude of slosh wave excitation, lowers the degree of asymmetry in the liquid–vapour distribution, and lowers angular momentum and fluid moment fluctuations.
