The drag reduction of the groove surface is inspired by the shark skin structures, the groove structure is transplanted onto the water-repellent robot and subjected to drag reduction simulation experiments. The effect of the width, height and apex angle of the V-shaped groove on the drag reduction coefficient is studied. When the dimensionless parameters of the width, height and apex angle of the groove are 16, 11and 70°, the best drag reduction effect is obtained, the drag reduction rate is about 6.5%. The characteristic parameters obtained through simulation experiments can provide a design basis for the drag reduction research of bionic water hammer robot.
