In order to study the influence mechanism of structural type and size on the hydrodynamic performance of vertical curved V-type otter board, this paper based on the computational fluid dynamics method, a three-dimensional numerical model of vertical curved V-type otter board is established to calculate and analyze its hydrodynamic performance, and the validity of the numerical simulation results is verified by designing and constructing a scaled model for dynamic flume experiments. On this basis, the effects of different structural parameters, such as the deflector angle, camber, and spacing, on the hydrodynamic performance of the vertical curved V-Type otter board are investigated and the optimal structural design scheme is determined. The results demonstrate that single or synchronous changes of the angle, camber, and spacing of the two deflectors have varying degrees of impact on the hydrodynamic performance of the vertical curved V-Type otter board. To improve the expansion effect of the otter board, setting the angle of the deflector A to 40° and that of the deflector B to 30°, or setting the camber of deflectors A and B to 18%, or setting the spacing between deflectors A and B to 380 mm and that between the deflector and the main panel to 670 mm can increase the lift coefficient of the vertical curved V-Type otter board to its maximum value. Considering the overall performance of the otter board, when the angle of the deflector A is set to 25° and that of the deflector B is set to 30°, or the camber of the deflector A is set to 6% and that of the deflector B is set to 9%, or the spacing between deflectors A and B is set to 340 mm and that between the deflector and the main panel is set to 610 mm, the lift-to-drag ratio of the otter board can be increased to its maximum value.
