T/4, (f) t = T/2, (g) t = 3T/4, (h) t = T, ωR = 5.0 r/s; θ0 = 80 .

3.2 Wall pressures

The time simulations of the pressure due to the liquid sloshing at different transducers are
presented in Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14 and Fig. 15. In the cases of the vertical
and T-shape baffled tank, except T4 for the un-baffled tank, the values of the pressure at T1, T2
and T3 behave almost periodically. At T4, the pressure is sensed when the roof impact occurs.
At this probe, the roof impact of the liquid doesn’t occur at any instant beyond the baffle height
of hB / h ≥ 0.65. As hB / h increases, the value of the maximum free surface elevation keeps
decreasing and does not reach the top wall due to the suppression of the liquid sloshing by the
hydrodynamic damping of the baffles.
