Sloshing in partially filled vehicle water tanks can induce large free-surface oscillations and dynamic loads following changes in vehicle motion. In this study, corrugated walls were applied to reduce sloshing without additional internal baffles. The amplitude A, number of waves N, and relative phase were varied, and 82 configurations were analyzed through two-dimensional transient Volume-of-Fluid (VOF) simulations using ANSYS Fluent. A 50% filling condition with acceleration from 0 to 6 s followed by constant-speed motion was considered. Sloshing performance was evaluated using the RMS and mean amplitude of the free-surface displacement. The results showed that the effect of the corrugated wall depended strongly on A, N, and phase arrangement, and some configurations showed poorer performance than the flat-wall tank. Among the tested cases, Out-Phase Case 41 exhibited the best overall free-surface behavior, with an RMS reduction of approximately 26.46%. These results indicate that corrugated-wall performance should be evaluated based on the geometric combination and phase arrangement rather than the presence of corrugation alone.
