Özet

This study experimentally investigates the passive control of free-surface sloshing in a partially filled rectangular tank using internal vertical baffles and introduces a novel MAX–MIN (Maximum–Minimum) image-processing method for sloshing analysis. The sloshing response is investigated across varying liquid depths, excitation frequencies, and baffle spacings, considering unbaffled conditions as well as single, dual, and triple baffle configurations. Quantitative evaluation of sloshing is first conducted using a virtual wave gauge, which provides time-history wave elevation data at a single reference point. In addition to this point-based evaluation, the proposed MAX–MIN approach offers a holistic, cross-sectional representation of free-surface motion. The method identifies maximum and minimum free-surface elevations in each frame over the considered time interval and combines them into a single composite image, enabling clear visualization of the extremal sloshing envelope. Experimental results show that internal vertical baffles significantly suppress wave amplitudes, particularly under near-resonant and post-resonant excitation conditions, with reductions up to 83% depending on the depth-to-baffle height ratio and spacing. The novel MAX–MIN method provides a robust and reliable full-field representation of sloshing extrema and offers valuable insights for the design of passive sloshing mitigation systems.
