Abstract: Cavitation damage widely exists in nuclear power plants. In order to reveal the mechanism of the cavitation damage in depth, this paper studies the dynamic behavior of the cavitation bubble at the asymmetric position near a right-angled convex wall based on the high-speed photographic experimental system. The contour deformation of the bubble, the moving distance and direction of the bubble centroid, and the change rule of the bubble jet direction with the relative position d and h of the bubble and the wall are analyzed in detail. The main conclusions of this paper are as follows:（1） The deformation of the bubble is related to the relative positions d and h. As the distance d between the bubble and the right wall increases, the asymmetry of the bubble becomes weaker. And as the distance h between the bubble and the upper wall increases, the non-spherical characteristics of the bubble gradually weaken during the entire dynamic process of the bubble.（2） During the collapse and regrowth of the bubble, the bubble centroid would continue to move to the lower left, and the moving distance of the bubble centroid decreases significantly with the increase of d and h.（3） When the distance h between the bubble and the upper wall is appropriate, there would be an obvious jet phenomenon towards the lower left, and the jet direction angle θ increases with the increase of d.
