カヌー競技用パドルのパドリング時における流れに関する研究

抄録

This research is conducted using with experiments and simulations to reproduce the flow loads corresponding to paddle movements in the development of land training equipment for canoeists. By comparing the results of experiments using a circular tank and a miniature model of a paddle blade with those of a simulation with a free interface, the validity of the simulation was verified and changes in the flow around the blade and forces on the paddle during paddling were investigated. Focused on the effect of changes in the angle of attack, the results are obtained such as the magnitude and direction of the force, pressure distribution, and velocity vectors. The results showed positive pressure in the downstream and negative pressure in the upstream of the paddle. The area of the negative pressure increases with the higher angle of attack. Since the force acts in the direction from positive pressure to negative pressure, it is thought that the lateral force tends to act in the negative direction, and the force measurement results show this tendency.
