Abstract—This study is focused on the interaction between a solitary wave and a bottom cavity with different aspect ratios. Vortex formations in cavity with different Reynolds numbers are considered. The moving trajectories of the primary vortex and the transportation of virtual fluid particles in the cavity are analyzed numerically. The numerical model is based on stream function-vorticity formulations, and the transient body-fitted grid combined with overset grid is adopted for grid systems. The numerical results were conducted through the comparisons with the experimental observations and measurements. Comparisons behave in good comparable tendency.
Index Terms—Solitary wave, cavity flow, viscous effect, particle motion.
