Abstract

The otter board is a vital component of single trawl system, of which the hydrodynamics can directly affect the trawl operation and catch performance. This paper studied the hydrodynamics of the rectangular otter board using numerical simulation, and the simulation accuracy was verified by flume tank experiment. In addition, the effect of different water layers on the hydrodynamics of the otter board is also studied. Experiment results show that the rectangular otter board has the maximum lift coefficient 1.070 with the flow angle attack at 40°. Simulation results have the similar tendency with experiment results, the simulation results of maximum lift coefficient is 1.227 ( =40°), which is similar to the experiment results, and the flow angle is the same as experiment results. Simulation study of different water layers show that the maximum lift coefficient and the critical angle in the free stream is bigger than that of in the bottom. The results can provide basis for the angle setting of the otter board while operating.
