“…An overset mesh scheme, which has been widely used by relevant scholars in simulating complex bodies with large amplitude motions [10][11][12][16][17][18][19][20][21], is applied to simulate the trimaran motions in waves. The computational fluid domain consists of a background region and an overset region, and the overset meshes are used for two regions to exchange data.…”

The main hull encounters waves at first and causes waves to break, when trimarans are subject to the slamming in head waves. At this moment, emergence phenomena of side hulls will not occur. Thus, the slamming study of trimarans in oblique waves presents further practical significance. In this study, a CFD method is used for trimaran seakeeping and slamming analysis. An overset grid technique is adopted to simulate ship motions in waves. Firstly, to further verify the present method, a series of verification and validation studies is conducted. Then, the motion responses and slamming pressure with different control parameters, such as forward speed and ship heading angle, are calculated and discussed. The comparative results indicate that the seakeeping and slamming behaviors of trimarans differ significantly from those of conventional monohull ships. Finally, severe bow slamming and green water in oblique waves are also observed and investigated, which should be given enough attention during ship design and evaluation.

“…Xu (2020) [4] used STAR-CCM+ to study the slamming load and motion response of the freak wave to the floating platform. Lin et al (2020) [5] used the improved Stavovy-Chuang model, CFD technique, and piecewise model experiments for the first time to predict the asymmetric impact accompanied by parametric rolling. Under the parametric rolling condition, the magnitude of the impact pressure decreases with the increase of wavelength, and the duration of the impact increases.…”

The Ultra Heavy-lift Amphibious Connector can be used for sea and land operations. When the amphibious connector opens the bow door, it will inevitably suffer from the combined action of wind, waves, currents, and other factors, resulting in the slamming of the wave on the hatch and various landing ship hull movements in the process. Due to the complexity of the actual UHAC model, in order to save computing resources, this paper selects the external load on the UAHC hatch when it is operated in water when the door is closed. The effects of crest height, draught, and focus position on UHAC slamming under the action of regular waves and freak waves were analyzed. Based on the viscous flow theory, the CFD commercial software FLUENT is used to simulate the interaction between the reduction of regular waves and floating structures. The simulation results are compared with the experimental results to verify the feasibility of the proposed method. Since the published UHAC data cannot be found in the network environment, this paper draws the UHAC based on the only data on the Internet and studies the slamming load of the wave on the UHAC on this basis.
